Antonio Augusto Villareal Acosta

Antonio Augusto Villarreal Acosta (born 1 September 1950, Morón, Cuba) is an economist, librarian, and Varela project coordinator. He published reports about problems of the transport facilities, the food supply and the housing shortage. Amnesty International declared him a prisoner of conscience. In 2007, International Society for Human Rights reported that he was in an acutely critical condition, having lost 60% of his former weight.

Villarreal was released on 13 July 2010 following an agreement between Fidel Castro, the Catholic Church, and the government of Spain. He then resettled in La Rioja, Spain.
