Miami Gardens is a city in north-central Miami-Dade County, Florida, United States. It is a suburb of Miami and located 16 miles (26 km) north of Downtown Miami with city boundaries that stretch from I-95 and Northeast 2nd Avenue to its east to Northwest 47th and Northwest 57th Avenues to its west, and from the Broward County line to its north to 151st Street to its south. The city's name originated from Florida State Road 860, a major roadway through the area also known as Miami Gardens Drive. It had a population of 111,640 as of 2020.

Miami Gardens is Florida's most populous city with a majority African American population and also home to the largest percentage of African Americans (66.97 percent) of any city in Florida, according to the U.S. Census Bureau. It is a principal city in the Miami metropolitan area of South Florida, which is the nation's ninth-largest, and world's 65th-largest metropolitan area with a population of 6.158 million people as of 2020. Miami Gardens is the home of Hard Rock Stadium, a 64,767 capacity multi-purpose stadium that serves as the home field for both the Miami Dolphins of the National Football League and the Miami Hurricanes, the University of Miami's NCAA Division I college football team.

In the wake of the construction of I-95 in the late 1960s, many middle- and upper-income African American and West Indian American families migrated from Miami neighborhoods like Liberty City to what became Miami Gardens (also called Carol City, Norland, or Norwood) as race-based covenants were outlawed with the Fair Housing Act, and mostly lower income blacks moved into the Liberty City and Little Haiti neighborhoods surrounding Liberty Square and Edison Courts.

Miami Gardens was incorporated on May 13, 2003. The city's neighborhoods of Andover, Bunche Park, Carol City, Lake Lucerne, Norland, Opa-locka North, and Scott Lake were previously unincorporated areas within Miami-Dade County.

In 2007, Mayor Shirley Gibson said that the city would no longer allow any low-income housing developments; many residents blamed the developments for spreading crime and recreational drugs throughout the city. Around that time, the city's tax revenues dropped to the third-lowest in Miami-Dade County.

In 2012, Oliver Gilbert, only the second mayor the city has had, proposed forming a community redevelopment agency (CRA). CRAs are formed to remove "slum and blight", to improve the physical environment of the city and to combat the social and economic problems typical of slum areas. CRAs are funded with property tax increases, which funds are used, in part, to stimulate private investment in the rehabilitation of the community.

During the 2026 FIFA World Cup, Hard Rock Stadium will host multiple matches during the tournament.

The Miami Gardens Police Department is the lead law enforcement agency for the 110,000 residents living within the city's 20 square miles (52 km2). The department operates under a unified command structure with its headquarters located at 1020 NW 163 Drive, Miami Gardens, Florida 33169.

Since then, the department has grown to 259 members consisting of 201 sworn positions with 58 non-sworn support positions.

In 2013, law enforcement abuses were alleged regarding the Miami Gardens Police Department by several news outlets. The abuses were first uncovered when it became public that a convenience store employee, Earl Sampson was arrested 27 times for trespassing, while working at and around the store at which he was employed. Video evidence was gathered by the owner of the store, Ali Saleh, showing Miami Garden police involved in clear and repeated misconduct involving his employee, and customers. According to the Miami Herald's Julie K. Brown: "The videos show, among other things, cops stopping citizens, questioning them, aggressively searching them and arresting them for trespassing when they have permission to be on the premises". It appeared Sampson had been arrested in this way due to police quotas, a department culture, and that Sampson was easy to arrest. Sampson always pleaded guilty so they would let him out almost immediately, with one exception where he pleaded not guilty, and he was jailed for 20 days. The guilty plea would validate the officers' improper arrest and increment their quota, so he became a continuous target.

It was reported that, between 2008 and 2013, 99,980 stops occurred in Miami Gardens, involving 56,922 people, over half of the city's population. In the City of Miami, 3,753 stops occurred during the same period, with four times the population. Some stops involved children aged 5 to 7, totaling more than 1,000 children. These numbers were compiled after news regarding Earl Sampson.

Following these reports, the police chief resigned. Civil rights lawsuits have been filed against the Miami Gardens Police Department by the store owner and others who were illegally detained and/or arrested. A police officer filed a lawsuit claiming that he had been fired for reporting abuses.
