The III South American Games (Spanish: Juegos Sudamericanos; Portuguese: Jogos Sul-Americanos) were a multi-sport event held in 1986 in Santiago, Chile, with some events in Concepción and Viña del Mar. The Games were organized by the South American Sports Organization (ODESUR) and were initially awarded to Guayaquil and Quito in Ecuador, but were moved due to lack of government support.
