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.

Hackbert initially focused on baseball. He spent a season playing baseball for the Grand Forks Chiefs; a Class C minor league team in the Pittsburgh Pirates organization. Vince Lombardi convinced Hackbart to drop baseball and concentrate on a career in the National Football League.^{[citation needed]}

In 1973, Hackbart was involved in an on-field transgression that he eventually took to court. He asserted that the late hit by Cincinnati Bengals running back Boobie Clark was an intentional tort. The case was eventually tried in the Tenth Circuit Court of Appeals in 1979 and has become a key point of discussion in several first year law school tort classes. Hackbart v. Cincinnati Bengals, Inc., 601 F.2d 516 (10th Cir. 1979)^{[citation needed]}
