Arnaldo Tomás Ochoa Sánchez (1930 – July 13, 1989) was a Cuban general who was executed by the government of Fidel Castro after being found guilty of a variety of crimes including drug smuggling and treason.

E. Bovo, the Curator of the Bay of Pigs Museum, claims that he was not a commander, rather that he served under 'El Gallego' José Ramón Fernández, a former officer under the Batista government.

Along with 15 other Cuban military was sent by Castro to strengthen Douglas Bravo guerrillas fighting the government of Raúl Leoni that ended in a major strategic loss at large rebel cost.

As the investigation continued, links were found to other military and Ministry of the Interior officials who were engaged in even more serious crimes: taking pay-offs from South American drug-traffickers, including Pablo Escobar and General Manuel Noriega in exchange for letting them use Cuban territorial waters for drug drops and pick-ups.

When Ochoa refused to cooperate, on June 12, the Ministry of the Revolutionary Armed Forces announced his arrest and investigation for serious acts of corruption, dishonest use of economic resources, and abetting drug trafficking.
