Leopoldo Fortunato Galtieri Castelli (15 July 1926 12 January 2003) was an Argentine general and politician. He served as President of Argentina from 22 December 1981 to 18 June 1982. This was during the last military dictatorship (known officially as the National Reorganization Process). He was removed from power soon after the British retook the Falkland Islands, whose invasion he had ordered.
