The 2011 Colombian regional and municipal elections were held on 30 October 2011, to elect the governors of 32 departments and their Department Assemblies, the mayors of 1,099 municipalities and their city councils, and the Local Administrative Juntas (JAL) of national territories.

A notable losing candidate was María Isabel Urrutia, an Olympic weightlifter who won Colombia's first gold medal in 2000; she unsuccessfully ran for mayor of Cali under the Alternative Democratic Pole.

A number of candidates for mayoral, municipal, and gubernatorial offices were alleged to have ties with paramilitaries.
