Miami-Dade Transit (MDT) is the primary public transit authority of Miami, Florida, United States and the greater Miami-Dade County area. It is the largest transit system in Florida and the 15th-largest transit system in the United States.  Ridership dropped 27% from 2010 to 2018. . From 2014 to 2018, each year there fewer riders than the prior year. 
MDT operates the Metrorail, Metromover, and Metrobus with their paratransit STS systems run by LSF. Metrorail is composed of two rail lines (Green and Orange lines) with 23 stations radiating from the city center towards outlying neighborhoods north and south of Downtown. Metromover operates throughout the Downtown, Omni, and Brickell neighborhoods, and is composed of three rail loops and 22 stations. Metrobus operates over 93 routes, including the South Dade Transitway.  MDT's main transit stations are Government Center in Downtown, and the Miami Intermodal Center in Grapeland Heights, which can access the Miami International Airport. 
As of 2011, MDT has a daily passenger ridership of 336,067, and accounts for over 15% of Miamians' daily transportation. MDT has seen growing passenger ridership since 1998, with ridership increasing 79% since then. The opening of the new Metrorail Orange Line in April 2012 is expected to significantly increase usage of the system.  Although not under the control of MDT, Tri-Rail is Miami-Dade's commuter rail system, and connects the Miami Intermodal Center & Tri-Rail Metrorail Transfer station to Fort Lauderdale and West Palm Beach. 
In 1960, the Dade County Commission passed an ordinance creating the Metropolitan Transit Authority (MTA) to unify the different transit operations into one countywide service. This ordinance provided for the purchase, development, and operation of an adequate mass transit system by the County. These companies included the Miami Transit Company, Miami Beach Railway Company, South Miami Coach Lines, and Keys Transit Company on Key Biscayne and would be managed by National City Management Company. National City was dismissed as manager in 1974.  Over the years and under various administrations, MTA evolved into the Metro-Dade Transportation Administration, the Metro-Dade Transit Agency, the Miami-Dade Transit Agency, and is now known simply as Miami-Dade Transit (MDT).
Miami-Dade Transit, a county department of more than 4,000 employees, is the largest transit agency in the state of Florida and accounts for more than half of the trips taken on public transit in the state. MDT operates an accessible, integrated system of 93-plus Metrobus routes; the 22-mile (35 km) Metrorail rapid transit system; Metromover, a free downtown people mover system; and the Paratransit division's Special Transportation Service. Metrobus routes cover more than 35-million miles annually, including limited service to Broward and Monroe counties. In 2004, MDT's Metrorail, Metromover, and Metrobus transported more than 96 million passengers, compared to 85 million the previous year.
Miami-Dade Transit was undergoing a federal investigation by the Federal Transit Administration that includes several audits and a criminal investigation of the transit agency due to concerns over money mismanagement within the agency.  This caused a freezing of federal funds being granted to the county agency. In late 2010 the county manager claimed that it was 'not fraud' but rather accounting errors, poor management, and erroneous information given to the auditors that triggered the investigation, including a withdrawal of $15 million through the ECHO program that was made by a transit official two hours after a letter arrived in September 2010 from the FTA telling them withdrawals had been restricted.  The investigation and lack of funding let to emergency service cuts to Metrorail, Metrobus, and Metromover being considered by the agency by the middle of 2011, six months into the investigation and lack of funding which began in November 2010, causing MDT to lose $185 million in grant money. Assistant county manager Ysela Llort became responsible for Miami-Dade Transit after director Harpal Kapoor left in April 2011. Additionally, funding for the Metrorail airport link was jeopardized by the funding freeze. The FTA decided to continue funding under strict control in order to keep service cuts from happening. 
- The Miami-Dade County Government has received federal money in order to purchase new railcars from Hitachi Rail Italy at a cost of $325 million.
- Technology and Corridor Improvements: Two corridors, totaling 24.4 miles (39.3 km) of rapid transit, have completed the planning phase and are ready to enter into final design and construction—the North Corridor, and East-West Corridor.
Metrorail serves the urban core of Miami, connecting the urban centers of Miami International Airport, the Civic Center, Downtown Miami, and Brickell with the northern developed neighborhoods of Hialeah and Medley to the northwest, and to suburban The Roads, Coconut Grove, Coral Gables, and South Miami, ending at Dadeland South in Kendall.
Metromover is a free, elevated, automated mass transit people mover that runs on three loops: the Downtown Inner Loop, Brickell Loop, and the Omni Loop. The systems total 4.4 miles (7.1 km) with 22 stations at roughly every two blocks in the greater Downtown area. Metromover serves the neighborhoods of Downtown, Arts & Entertainment District, Brickell, Park West, and Overtown.
The Metrobus network provides bus service throughout Miami-Dade County 365 days a year. It consists of about 93 routes and 880 buses, which connect most points in the county and part of southern Broward County as well. Seven of these routes operate around the clock: Routes 3, 11, 27, 38, 77 (last bus from Downtown Miami 1:10am, first bus from Downtown Miami 4:10am), L (No 24-hour service to Hialeah, all trips terminate at Northside Station) and S. Routes 246 Night Owl (served by LSF) & Route 500 Midnight Owl (County operated) which operate from 12am to 5am. Most other routes operate from 4:30am to 1:30am. All Metrobuses are wheelchair accessible, in compliance with the Americans with Disabilities Act of 1990 and all county buses except for private run routes are equipped with Bicycle racks. Some privatized routes trucks are receiving bike racks but very limited.
Bus route 301 (Dade-Monroe Express) extends into Monroe County, reaching Marathon, where a transfer is available to a Key West Transit bus proceeding further into the Keys. With the appropriate bus transfers, one can travel all the way from Key West to Jupiter entirely on public-transit buses.

For $3 per one-way trip, STS offers shared-ride, door-to-door travel in accessible vehicles throughout most of Miami-Dade County, in some parts of south Broward County, and in the middle and northern Keys. STS operates 24 hours a day, 7 days a week, including most holidays. Service is run by private company.
