Marcos Evangelista Pérez Jiménez (25 April 1914 – 20 September 2001) was a Venezuelan military and general officer of the Army of Venezuela and the dictator of Venezuela from 1950 to 1958, ruling as member of the military junta from 1950 to 1952 and as president from 1952 to 1958. He took part in the 1948 coup d'état, becoming part of the ruling junta. He ran in the 1952 election. However, the junta cancelled the election when early results indicated that the opposition was ahead, and declared Jiménez provisional president. He became president in 1953 and instituted a constitution that granted him dictatorial powers.
