Duval County is located in the northeastern part of the U.S. state of Florida. As of the 2010 census, the population was 864,263, with a 2019 estimate at 957,755, the seventh most populous in Florida.   Its county seat is Jacksonville, with which the Duval County government has been consolidated since 1968.  Duval County was established in 1822, and is named for William Pope Duval, Governor of Florida Territory from 1822 to 1834.
Duval County is included in the Jacksonville, FL Metropolitan Statistical Area.
This area had been settled by varying cultures of indigenous peoples for thousands of years before European contact. Within the Timucuan Ecological and Historic Preserve in Jacksonville, archeologists have excavated remains of some of the oldest pottery in the United States, dating to 2500 BCE. Prior to European contact, the area was inhabited by the Mocama, a Timucuan-speaking group who lived throughout the coastal areas of northern Florida.  At the time Europeans arrived, much of what is now Duval County was controlled by the Saturiwa, one of the region's most powerful tribes. The area that became Duval County was home to the 16th-century French colony of Fort Caroline, and saw increased European settlement in the 18th century with the establishment of Cowford, later renamed Jacksonville.
Duval County was created in 1822 from St. Johns County. It was named for William Pope Duval, Governor of Florida Territory from 1822 to 1834.  When Duval County was created, it covered a massive area, from the Suwannee River on the west to the Atlantic Ocean on the east, north of a line from the mouth of the Suwannee River to Jacksonville on the St. Johns River. Alachua and Nassau counties were created out of parts of Duval County in 1824. Clay County was created from part of Duval County in 1858. Part of St. Johns County south and east of the lower reaches of the St. Johns River was transferred to Duval County in the 1840s. 
On October 1, 1968, the government of Duval County was consolidated with the government of the city of Jacksonville. The Duval County cities of Atlantic Beach, Jacksonville Beach, and Neptune Beach, and the town of Baldwin are not included in the corporate limits of Jacksonville, and maintain their own municipal governments. The city of Jacksonville provides all services that a county government would normally provide.
According to the U.S. Census Bureau, the county has an area of 918 square miles (2,380 km2), of which 762 square miles (1,970 km2) is land and 156 square miles (400 km2) (17.0%) is water.  The topography is coastal plain; however there are some rolling hills.

Duval County is somewhat conservative for an urban county. It began moving away from the Democratic Party somewhat sooner than the rest of Florida. Despite the small Democratic plurality in registration, the county's Democrats are nowhere near as liberal as their counterparts in other large Florida counties, such as Miami-Dade and Orange. The county has only supported a Democrat for president thrice since 1956, in 1960, 1976, and 2020.
However, the Republican edge in Duval has lessened somewhat in recent years. It swing from a 16-point win for George W. Bush in 2004 to only a three-point win for John McCain in 2008. Mitt Romney won an equally narrow margin in 2012 and in 2016, Donald Trump only won the county by fewer than 6,000 votes even as he narrowly carried Florida. In 2020, Joe Biden, despite losing statewide, finally broke the 44-year Democratic drought in Duval county, winning by less than four points.
In 2018, Andrew Gillum, despite losing the election, won Duval by 4 points, the first time a Democrat has won the county in a gubernatorial election since Steve Pajcic's losing bid in 1986. In the Senate elections, Bill Nelson only failed to carry the county in his first bid in 2000, and Lawton Chiles and Bob Graham have carried the county in all three of their respective bids.
