Roberto Maestas (July 9, 1938 – September 22, 2010) was an American social activist who was prominent between the 1960s and the 1990s in Seattle, Washington.

Maestas was a member of the Gang of Four and one of the founders of El Centro de la Raza.

[1][2] Maestas was born in rural New Mexico and raised by his grandparents and after working throughout the Western United States as a migrant worker eventually settled in Seattle in the 1950s.

In the early 1970s he helped begin an ESL program at South Seattle College.

In 1972, funding to the program was abruptly cut off which led to Maestas and a number of other activists to occupy an abandoned school building in Seattle's Beacon Hill neighborhood which eventually became El Centro de la Raza.
