The Miami Police Department (MPD), also known as the City of Miami Police Department, is a full-service municipal law enforcement agency serving the city of Miami, Florida, United States. MPD is the largest municipal police department in Florida. MPD officers are distinguishable from their Miami-Dade Police Department counterparts by their blue uniforms and blue-and-white patrol vehicles.

MPD operates the Miami Police College, which houses three schools: The Police Academy Class (PAC), The School for Professional Development (SPD), and the International Policing Institute (IPI), a program focused on training law enforcement personnel from countries outside of the United States.

In its early years, the MPD enacted an oppressive racial system in Miami. The MPD did not protect the black community from violence, as well as aided in the harassment and terrorization of the black population. The MPD intimidated black voters, pursued blacks on flimsy evidence, and strongly enforced certain laws solely when blacks were in violation of them. The MPD tacitly approved of or failed to investigate instances of white supremacist violence in Miami by terrorist groups such as the Ku Klux Klan.

In January 1986, The New York Times reported that "corruption charges are not new" to MPD.

In 2018, the Miami New Times wrote, "Miami cops have a storied history of getting caught committing the very crimes they are supposed to police."

Jorge Colina became MPD Chief of Police in 2018. In March 2021, Art Acevedo became Miami Police Department chief. Prior to this role, he served as the chief of police in Houston. Art Acevedo was fired on October 14, 2021

The U.S. Department of Justice (DOJ) investigated the Miami Police Department twice, once beginning in 2002 and once from 2011–2013.

The investigation by DOJ's Civil Rights Division and the U.S. Attorney's Office for the Southern District of Florida that was completed in 2013 was prompted by a series of incidents over eight months in 2011 in which Miami officers fatally shot seven young black men. The DOJ investigation concluded that the Miami Police Department "engaged in a pattern or practice of excessive use of force through officer-involved shootings in violation of the Fourth Amendment of the Constitution." The investigation reached many of the same conclusions as the 2002 investigation. It found that MPD officers had intentionally fired upon individuals on 33 occasions between 2008 and 2011, and that the MPD itself found that the shootings were unjustified on three occasions. The DOJ also determined that "a number of MPD practices, including deficient tactics, improper actions by specialized units, as well as egregious delays and substantive deficiencies in deadly force investigations, contributed to the pattern or practice of excessive force." The DOJ found that MPD had failed to "complete thorough, objective and timely investigations of officer-involved shootings" and sometimes failed to reach a conclusion "as to whether or not the officer's firearm discharge was lawful and within policy," which the DOJ cited as a factor that "undermined accountability and exposed MPD officers and the community to unreasonable risks that might have been addressed through prompt corrective action." The DOJ also found that "a small number of officers were involved in a disproportionate number of shootings, while the investigations into their shootings continued to be egregiously delayed."
