Silvius Magnago (February 5, 1914 – May 25, 2010) was a South Tyrolean Italian politician.
Magnago was born in Meran/Merano. He studied law at the University of Bologna and graduated with a JD in June 1940. Because of its rejection of Italian Fascism he chose to move to Germany in 1939, but remained first in South Tyrol, where he worked in Bolzano for a commission to estimate the assets of the Tyroleans following the South Tyrol Option Agreement. He was eventually called in the German Army as a lieutenant, and was sent to the Eastern Front. He was chairman of the South Tyrolean People's Party (1957–1991) and governor (Landeshauptmann) of the autonomous province of South Tyrol from 1960 to 1989.
He died in Bolzano/Bozen on May 25, 2010.
