Stuart Alan "Stu" Voigt (born August 12, 1948) is a former American football player, a tight end in the National Football League for eleven season with the Minnesota Vikings.
Born in the Westmorland district of Madison, Wisconsin, he graduated from Madison West High School in 1966, where he was an all-state running back and track and field standout.
His state record in shot put of 66 ft 7 in (20.29 m) in 1966 stood for 39 years.
He accepted a football scholarship to the University of Wisconsin–Madison and was a star halfback and tight end on some of the worst teams in Badger history, which won just three games in his three varsity years of 1967–1969, all in his senior season.
In the 1970 NFL Draft, Voigt was selected in the tenth round by the Vikings and played in three Super Bowls (VIII, IX, XI), all losses.
He retired after the 1980 season, and was a color commentator on Vikings radio broadcasts from 1981–1990 and 1997–2000.
