Olga Costa (Leipzig, Alemania, 1913 - Guanajuato, 1993), born into an Ukrainian family as  Olga Kostakowsky Fabrikant, was a prominent painter and cultural manager. She arrived in Mexico with her family in 1925, fleeing political persecution due to her father's socialist activism, for which he was imprisoned and later granted amnesty. She studied at the Escuela Nacional de Artes Plásticas (National School of Fine Arts), where she was a student of Carlos Mérida and Emilio Amero. 

In 1935, she married the painter José Chávez Morado, with whom she shared her political and artistic commitment. She was the founder of important cultural spaces such as the Galería Espiral (Spiral Gallery) in 1941 and the Sociedad de Arte Moderno (Modern Art Society) in 1943. Along with Chávez Morado, she founded the Museo del Pueblo de Guanajuato (Museum of the Town of Guanajuato) in 1979. She was awarded the National Prize for Arts and Sciences in 1990, and her tireless work in art management has awarded her high honors in various museums and festivals, testifying her lasting legacy in Mexican culture.

Her pictorial work, characterized by vibrant use of color and themes such as landscapes, still lifes, and portraits, is part of important collections; among the most emblematic pieces is Vendedora de frutas (1951), housed at the Museo de Arte Moderno (Museum of Modern Art).
