Marilina Ross (born María Celina Parrondo, February 16, 1943, Liniers, Buenos Aires) is an Argentine singer and actress. She went into exile in Spain during the years of the military dictatorship (1976–1983), because this would not allow her to develop her artistic activities in Argentina.
Ex-spouse of actor Emilio Alfaro, she is a friend of the actresses Norma Aleandro, Cristina Banegas, Selva Alemán, singer Piero and writer Alberto Migré. Also, she was a friend of the late actress Bárbara Mujica, with whom she shared several works.
