Dale Leonard Hackbart (born July 21, 1938 in Madison, Wisconsin) is a former American football defensive back who played twelve seasons in the National Football League for the Green Bay Packers, Washington Redskins, Minnesota Vikings, St. Louis Cardinals, and Denver Broncos from 1960 to 1973. He also played in the Canadian Football League for the Winnipeg Blue Bombers in 1964 and 1965. In 1973, Hackbart was involved in an on-field transgression that he eventually took to court. He asserted that a late hit by Cincinnati Bengals running back Boobie Clark was an intentional tort.
