Aida de la Fuente Penaos (25 February 1915 in León – 13 October 1934 in Oviedo), better known as Aida Lafuente, was a Spanish communist militant who died in the Revolution of 1934 in Asturias after the repression by the Second Spanish Republic.

Aida, along with her brothers, was an active participant in the organization of the Communist Youth of Spain.

After the outbreak of the Civil War, Aida Lafuente's name appeared on propaganda posters.

In October 1936, the 1st Asturian Battalion was renamed in honor of Lafuente, and a street with her name appeared in Gijón.

[2] Alejandro Medushevsky (born 1969), the great-nephew of Lafuente, led a pro-Russian militia during the Annexation of Crimea by the Russian Federation in 2014.
