Bruce Edward Hart (born January 13, 1950) is an American-born Canadian retired professional wrestler, promoter, booker, trainer and school teacher. He is a second-generation wrestler and a member of the Hart wrestling family, being the second child of Stu and Helen Hart. He is best known for his time in Stampede Wrestling and several appearances for WWE, often with his brothers Bret and Owen.

As a wrestler Hart carried a number of championships, including the Stampede North American Heavyweight Championship and participated in WWF's Survivor Series.

While his mother was pregnant with Hart she and her husband Stu suffered an automobile accident. This resulted in his older brother Smith being cared for by their maternal grandparents for almost two years while Helen recovered in the hospital.

He is of Greek descent through his maternal grandmother and Irish through his maternal grandfather. His father was mainly of Scots-Irish descent but also had Scottish and English ancestry. Hart is a dual citizen of Canada and the United States.

Bruce Hart began his wrestling training in 1971, at the age of 21, in his father's training school "The Dungeon". Trained by Stu Hart, Bruce, like the rest of his family, was trained in and focused on a technically sound, amateur wrestling style.

He debuted in 1972, in his fathers Calgary promotion, Stampede Wrestling, tag teaming with Dan Kroffat in the main event, against North American Champion Kendo Nagasaki (the original masked British version) and his manager "Gorgeous" George Gillette (billed in Canada as "Lord Sloane of Kensington Gore".) For the next six months he remained a headline performer for the promotion, working against the likes of John Quinn, Benny Ramirez, Frank Butcher, Tor Kamata, Chatti Yokuchi and Yasu Fuji. In June 1973, he suffered a serious shoulder injury which sidelined him for 9 months and nearly finished his career. He returned in the summer of 1974, and continued as performer in Western Canada. Hart kept wrestling on and off but had relatively few matches until after 1977.

He traveled to the United Kingdom in 1977, where he wrestled under the name "Bronco" Bruce Hart for the London/Halifax based Joint Promotions.

While there, he met a young Tom Billington and offered him an opportunity to wrestle for Stampede, which Billington declined. After a falling out with Joint Promotions, Billington, using the ring name Dynamite Kid, traveled to Canada and joined Stampede. Dynamite quickly became a huge star in Western Canada. As a result, Hart invited Billington's younger cousin, David Smith, to also come to Western Canada. Smith, who originally wrestled as Young David, later became known as Davey Boy Smith (after British lightweight boxing champion - Dave Boy Green) after Hart decided that it was a better ring name.
