General Guido Hernán Vildoso Calderón (born 5 April 1937) is a Bolivian retired military officer who served as the 59th president of Bolivia from July to October 1982.

Born in La Paz on 5 April 1937, Vildoso joined the Bolivian armed forces and took specialized courses in Brazil, Panama, and the United States.

Vildoso was second in command in the Bolivian Army when, in July 1982, he was entrusted by his peers with the task of extricating the military from power and returning the country to constitutional, democratic rule after a period of several dictatorships.

When it became apparent that the country would crumble into civil war before new elections could be held, Vildoso's junta recalled the 1980 Congress and promised to accept its choice of president.

Congress reconvened on 23 September, and its virtual first act was to reconfirm the 1980 election results, which showed former president Hernán Siles Zuazo well ahead, though short of a majority.
