Antonio Veciana Blanch (October 18, 1928 – June 18, 2020) was a Cuban exile who became the founder and a leader of the anti-Castro group Alpha 66.

He also claimed that he met a man he later recognized to be Lee Harvey Oswald during a meeting with Bishop about two to three months prior to the assassination of United States President John F. Kennedy.

[4] Veciana said he was recruited as a spy for the CIA by David Atlee Phillips (also known as Maurice Bishop) in 1959 to kill Fidel Castro.

[4] Alpha 66 became one of the most active Cuban exile groups, acquiring guns and boats and launching commando raids on Cuba.

This included another assassination attempt on Castro in Chile in 1971[4] involving a plan to put a gun inside a television camera.

Veciana's recruiting of Cuban associates who prepared a plan to blame Russian agents for the assassination led to a falling-out with Bishop and the eventual termination of their relationship.

[4] On July 24, 1973, Veciana was arrested in Miami on charges related to smuggling 25 kilograms of pure cocaine from Bolivia into the United States with two other co-conspirators who had also fled to Florida from Cuba after Castro came to power, Augustin Barres and Ariel Pomares.
