Juan Salvador Guzmán Tapia (Spanish pronunciation: [xwaŋ ɡuzˈman ˈtapja]; 22 April 1939 – 22 January 2021) was a Chilean judge. He was the first Chilean judge to lead investigations and prosecute Augusto Pinochet for violations of human rights during his dictatorship between 1973 and 1990. As a special prosecutor, he used novel legal strategies to hold Pinochet and members of his military regime accountable for the killings and human rights violations during this period.
