Honolulu ( //;  Hawaiian: [honoˈlulu]) is the capital and largest city of the U.S. state of Hawaii. It is an unincorporated part of and the county seat of the City and County of Honolulu along the southeast coast of the island of Oʻahu. [a] The city is the main gateway to Hawaiʻi and a major portal into the United States. The city is also a major hub for international business and military defense, as well as being host to a diverse variety of east-west and Pacific cultures, cuisine, and traditions.
Honolulu is the remotest city of its size in the world,  and is the westernmost and southernmost major U.S. city. For statistical purposes, the United States Census Bureau recognizes the approximate area commonly referred to as "City of Honolulu" (not to be confused with the "City and County") as a census county division (CCD).  Honolulu is a major financial center of the islands and of the Pacific Ocean. The population of the Honolulu census designated place (CDP) was 359,870 as of the 2017 population estimate,  while the Honolulu CCD was 390,738  and the population of the consolidated city and county was 953,207.
Honolulu means "sheltered harbor"  or "calm port" in Hawaiian.  The old name is Kou, a district roughly encompassing the area from Nuʻuanu Avenue to Alakea Street and from Hotel Street to Queen Street which is the heart of the present downtown district.  The city has been the capital of the Hawaiian Islands since 1845 and gained historical recognition following the attack on Pearl Harbor by Japan near the city on December 7, 1941.
As of 2015 [update], Honolulu was ranked high on world livability rankings, and was also ranked as the 2nd safest city in the U.S.   It is also the most populated Oceanian city outside Australasia and ranks second to Auckland as the most-populous city in Polynesia.

Evidence of the first settlement of Honolulu by the original Polynesian migrants to the archipelago comes from oral histories and artifacts. These indicate that there was a settlement where Honolulu now stands in the 11th century.  After Kamehameha I conquered Oʻahu in the Battle of Nuʻuanu at Nuʻuanu Pali, he moved his royal court from the Island of Hawaiʻi to Waikīkī in 1804. His court relocated in 1809 to what is now downtown Honolulu. The capital was moved back to Kailua-Kona in 1812.
In 1794, Captain William Brown of Great Britain was the first foreigner to sail into what is now Honolulu Harbor.  More foreign ships followed, making the port of Honolulu a focal point for merchant ships traveling between North America and Asia.
In 1845, Kamehameha III moved the permanent capital of the Hawaiian Kingdom from Lahaina on Maui to Honolulu. He and the kings that followed him transformed Honolulu into a modern capital,  erecting buildings such as St. Andrew's Cathedral, ʻIolani Palace, and Aliʻiōlani Hale. At the same time, Honolulu became the center of commerce in the islands, with descendants of American missionaries establishing major businesses in downtown Honolulu. 
Despite the turbulent history of the late 19th century and early 20th century, such as the overthrow of the Hawaiian monarchy in 1893, Hawaiʻi's subsequent annexation by the United States in 1898, followed by a large fire in 1900, and the Japanese attack on Pearl Harbor in 1941, Honolulu remained the capital, largest city, and main airport and seaport of the Hawaiian Islands. 
An economic and tourism boom following statehood brought rapid economic growth to Honolulu and Hawaiʻi. Modern air travel brings, as of 2007 [update], 7.6 million visitors annually to the islands, with 62.3% entering at Honolulu International Airport.  Today, Honolulu is a modern city with numerous high-rise buildings, and Waikīkī is the center of the tourism industry in Hawaiʻi, with thousands of hotel rooms. The UK consulting firm Mercer, in a 2009 assessment "conducted to help governments and major companies place employees on international assignments", ranked Honolulu 29th worldwide in quality of living; the survey factored in political stability, personal freedom, sanitation, crime, housing, the natural environment, recreation, banking facilities, availability of consumer goods, education, and public services including transportation. 
According to the United States Census Bureau, the Urban Honolulu Census-designated place (CDP) has a total area of 68.4 square miles (177.2 km2). 60.5 square miles (156.7 km2) of it (88.44%) is land, and 7.9 square miles (20.5 km2) of it (11.56%) is water. 
Honolulu is the remotest major city in the world.  The closest location on the mainland to Honolulu is the Point Arena Lighthouse in California, at 2,045 nautical miles (3,787 km).  ( Nautical vessels require some additional distance to circumnavigate Makapuʻu Point.) However, islands off the Mexican coast, and part of the Aleutian Islands of Alaska are slightly closer to Honolulu than the mainland. The volcanic field of the Honolulu Volcanics is partially located inside the city. 
- Downtown Honolulu is the financial, commercial, and governmental center of Hawaiʻi. On the waterfront is Aloha Tower, which for many years was the tallest building in Hawaiʻi. Currently the tallest building is the 438-foot (134 m) tall First Hawaiian Center, located on King and Bishop Streets. The downtown campus of Hawaiʻi Pacific University is also located there.
- The Arts District Honolulu, located in both in downtown and Chinatown, is on the eastern edge of Chinatown.

Burns School of Medicine, part of the University of Hawaiʻi at Mānoa, is also located there. A Memorial to the Ehime Maru Incident victims is built at the Kakaʻako Waterfront Park.
- Ala Moana is a district between Kakaʻako and Waikīkī and the home of Ala Moana Center, the "World's largest open-air shopping center" and the largest shopping mall in Hawaiʻi.  Ala Moana Center boasts over 300 tenants and is a very popular location among tourists. Also in Ala Moana is the Honolulu Design Center and Ala Moana Beach Park, the second largest park in Honolulu.
- Waikīkī is the tourist district of Honolulu, located between the Ala Wai Canal and the Pacific Ocean next to Diamond Head.

Kaimukī is primarily a residential neighborhood with a commercial strip centered on Waiʻalae Avenue running behind Diamond Head. Chaminade University is located in Kaimukī.
- Waiʻalae and Kāhala are upper-class districts of Honolulu located directly east of Diamond Head, where there are many high-priced homes. Also found in these neighborhoods are the Waialae Country Club and the five-star Kahala Hotel & Resort.
- East Honolulu includes the residential communities of ʻĀina Haina, Niu Valley, and Hawaiʻi Kai. These are considered upper-middle-class neighborhoods. The upscale gated communities of Waiʻalae ʻIki and Hawaiʻi Loa Ridge are also located here.
- Kalihi and Pālama are working-class neighborhoods with a number of government housing developments. Lower Kalihi, toward the ocean, is a light-industrial district.
- Salt Lake and Āliamanu are (mostly) residential areas built in extinct tuff cones along the western end of the Honolulu District, not far from the Honolulu International Airport.
- Moanalua is two neighborhoods and a valley at the western end of Honolulu, and home to Tripler Army Medical Center.
Honolulu experiences a Tropical semi-arid climate ( Köppen classification BSh), with a mostly dry summer season, due to a rain shadow effect.  Temperatures vary little throughout the months, with average high temperatures of 80–90 °F (27–32 °C) and average lows of 65–75 °F (18–24 °C) throughout the year. Temperatures reach or exceed 90 °F (32 °C) on an average 38 days annually,  [b] with lows in the upper 50s °F (14–15 °C) occurring once or twice a year. The highest recorded temperature was 95 °F (35 °C) on September 19, 1994 and August 31, 2019.  On the former date, the highest recorded temperature in the state was also recorded later that day in Niʻihau. The lowest recorded temperature was 52 °F (11 °C) on February 16, 1902, and January 20, 1969.  With high temperatures and humidity, there is a vast tropical influence on the climate, although rainfall falls short of that classification.
The annual average rainfall is 17.10 inches (434 millimeters),  which mainly occurs during the winter months of October through early April, with very little rainfall during the summer. However, both seasons experience a similar number of rainy days. Light showers occur in summer, while heavier rain falls during winter. Honolulu has an average of 278 sunny days and 90 rainy days per year.
Although the city is situated in the tropics, hurricanes are quite rare. The last recorded hurricane that hit near Honolulu was Category 4 Hurricane Iniki in 1992. Tornadoes are also uncommon and usually strike once every 15 years. Waterspouts off the coast are also uncommon, hitting about once every five years. 
The average temperature of the sea ranges from 75.7 °F (24.3 °C) in March to 80.4 °F (26.9 °C) in September.

Honolulu has been ranked as having the nation's worst traffic congestion, beating former record holder Los Angeles. Drivers waste on average over 58 hours per year on congested roadways.  The following freeways, part of the Interstate Highway System serve Honolulu:
- Interstate H-1, which, coming into the city from the west, passes Hickam Air Force Base and Honolulu International Airport, runs just north of Downtown and continues eastward through Makiki and Kaimuki, ending at Waialae/Kahala. H-1 connects to Interstate H-2 from Wahiawa and Interstate H-3 from Kaneohe, west of the CDP.
- Interstate H-201—also known as the Moanalua Freeway and sometimes numbered as its former number, Hawaiʻi State Rte. 78—connects two points along H-1: at Aloha Stadium and Fort Shafter. Close to H-1 and Aloha Stadium, H-201 has an exchange with the western terminus of Interstate H-3 to the windward side of Oahu ( Kaneohe). This complex of connecting ramps, some directly between H-1 and H-3, is in Halawa.
Other major highways that link Honolulu CCD with other parts of the Island of Oahu are:
- Pali Highway, State Rte. 61, crosses north over the Koolau range via the Pali Tunnels to connect to Kailua and Kaneohe on the windward side of the Island.
- Likelike Highway, State Rte. 63, also crosses the Koolau to Kaneohe via the Wilson Tunnels.
- Kalanianaole Highway, State Rte. 72, runs eastward from Waialae/Kahala to Hawaiʻi Kai and around the east end of the island to Waimanalo Beach.
- Kamehameha Highway, State Rts. 80, 83, 99 and 830, runs westward from near Hickam Air Force Base to Aiea and beyond, eventually running through the center of the island and ending in Kaneohe.
Like most major American cities, the Honolulu metropolitan area experiences heavy traffic congestion during rush hours, especially to and from the western suburbs of Kapolei, ʻEwa Beach, Aiea, Pearl City, Waipahu, and Mililani.
There is a Hawaiʻi Electric Vehicle Demonstration Project (HEVDP). 
In November 2010, voters approved a charter amendment to create a public transit authority to oversee the planning, construction, operation and future extensions to Honolulu's future rail system. The Honolulu Authority for Rapid Transportation (HART) currently includes a 10-member board of directors; three members appointed by the mayor, three members selected by the Honolulu City Council, and the city and state transportation directors.  The opening of the Honolulu Rail Transit is delayed until approximately 2020, as HART canceled the initial bids for the first nine stations and intends to rebid the work as three packages of three stations each, and allow more time for construction in the hope that increased competition on smaller contracts will drive down costs;  initial bids ranged from $294.5 million to $320.8 million, far surpassing HART's budget of $184 million. 
Established by former Mayor Frank F. Fasi as the replacement for the Honolulu Rapid Transit Company (HRT), Honolulu's TheBus system was honored in 1994–1995 and 2000–2001 by the American Public Transportation Association as "America's Best Transit System". TheBus operates 107 routes serving Honolulu and most major cities and towns on Oʻahu. TheBus comprises a fleet of 531 buses, and is run by the non-profit corporation Oʻahu Transit Services in conjunction with the city Department of Transportation Services. Honolulu is ranked 4th for highest per-capita use of mass transit in the United States. 
The island also features TheHandi-Van . available for riders who require para transit operations. To be eligible for these parantransit service, individuals must meet the requirements of the Americans with Disabilities Act (ADA). TheHandi-Van has a fare of $2.00, available Mondays - Sundays from 4:00 am - 1:00 am. There is a 24 hours per day service but only within 3/4 of a mile of TheBus route 2  and route 40 . TheHandi-Van comprises a fleet of 160 buses. Additionally the parantransit branch also run's Human Services Transportation Coordination (HSTCP), which mainly provides transportation for people with disabilities, older adults, and people with limited incomes, assisted by the Committee for Accessible Transportation (CAT). Both organizations work together to provide transportation for elderly and persons with disabilities.
Currently, there is no urban rail transit system in Honolulu, although electric street railways were operated in Honolulu by the now-defunct Honolulu Rapid Transit Company prior to World War II. Predecessors to the Honolulu Rapid Transit Company were the Honolulu Rapid Transit and Land Company (began 1903) and Hawaiian Tramways (began 1888). 
The City and County of Honolulu is currently constructing a 20-mile (32 km) rail transit line that will connect Honolulu with cities and suburban areas near Pearl Harbor and in the Leeward and West Oahu regions. The Honolulu High-Capacity Transit Corridor Project is aimed at alleviating traffic congestion for West Oʻahu commuters while being integral in the westward expansion of the metropolitan area. The project, however, has been criticized by opponents of rail for its cost, delays, and potential environmental impacts, but the line is expected to have large ridership.
Since June 28, 2017, Bikeshare Hawaii administers the bicycle sharing program in O'ahu while Secure Bike Share operates the Biki system. Most Biki stations are located between Chinatown/Downtown and Diamond Head, however an expansion in late 2018 added more stations towards the University of Hawai'i Manoa Campus, Kapi'olani Community College, Makiki, and Kalihi area.     The GoBiki.org website has a Biki stations map.
According to the 2016 American Community Survey (five-year average), 56 percent of Urban Honolulu residents commuted to work by driving alone, 13.8 percent carpooled, 11.7 used public transportation, and 8.7 percent walked.
