Mario Abel Amaya (August 3, 1935, Dolavon, Chubut - October 19, 1976, Buenos Aires) was an Argentine lawyer and politician, reformist activist at the university and a member of the Radical Civic Union that was arrested-disappeared in 1976 by the V Army Corps based in Bahía Blanca, dying as a result of the torture to which it was subjected.

Upon receiving a lawyer, he settled in Trelew, installing his law firm together with Patricio "el Oso" Romero, a prominent Peronist leader.

In 1972 there was a flight of political prisoners from the Montonero guerrilla organizations and Revolutionary People's Army, during which a large group was trapped in the Trelew airport.

As a product of their struggles, they began to appear on the blacklists of intolerance, which the information services themselves and their terrorist groups, such as the Triple A, made public with the purpose of intimidation.
