Atlético Madrid C was a Spanish football club that played in the Tercera División and played their home games at the Nuevo Cerro del Espino.

In 1972, both a C-team of Atlético Madrid and Amorós were founded separately, with the former club being named Club Atlético de Madrid Aficionados and the latter club being named Asociación de Padres de Alumnos Colegio Amorós.

In 1976, Atlético Madrid Aficionados was renamed Atlético Madrileño Club de Fútbol Aficionado, and ceased activities in 1985 after three seasons in Tercera División.

In 2005, Atlético Aviación changed name to Club Atlético de Madrid C. In April 2015, after the relegation of Atlético Madrid B to the fourth division, Atleti C ceased activities.
