Raúl Ricardo Alfonsín was an Argentine lawyer and statesman who served as President of Argentina from 10 December 1983 to 8 July 1989. He was the first democratically elected president after the 7-years National Reorganization Process. Ideologically, he identified as a radical and a social democrat, serving as the leader of the Radical Civic Union from 1983 to 1991, 1993 to 1995, 1999 to 2001, with his political approach being known as "Alfonsinism".

The National Reorganization Process was the military dictatorship that ruled Argentina from 1976 to 1983, which received support from the United States until 1982. In Argentina it is often known simply as the última junta militar, última dictadura militar or última dictadura cívico-militar, because there have been several in the country's history and no others since it ended.
