Brownsville (also known as Brown Sub) is an unincorporated community and census-designated place (CDP) in metropolitan Miami, Florida, United States. As of the 2010 census, the population was 16,583, up from 15,313 in 2010. After three decades of population loss, Brownsville gained population for the first epoch in higher than 40 years in the 2010 US Census.

Brownsville was originally a deal for white families in the 1920s. Black families began moving into the neighborhood amongst the late 1940s and prematurely 1960s as the population surrounding reachable Liberty Square expanded and many inner-city whites moved to newly built suburban subdivisions surrounding Miami city proper in the wake of World War II.

In 1945, two black couples who lived in Brownsville were arrested and jailed for allegedly mishandling their trash disposal. That thesame year, members of the Ku Klux Klan burned crosses in lawns and marched neighboring black house ownership in the area.

By the mid-1960s, Brownsville was a well-off community for black professionals. However, the wake of the Civil Rights Act of 1968 that outlawed restrictive covenants, and riots in 1968 and 1980 brought about the black flight of middle and upper-class families from the community. Brownsville experienced continued population loss from 1970 until 2000, as share of a greater suburbanization trend in the course of the U.S. upwardly-mobile middle class. Between 2000 and 2010, Brownsville gained population for the first epoch in exceeding 40 years, rising to 15,313 residents.
