Stewart Edward (Stu) Hart (May 3, 1915 - October 16, 2003) was a Canadian wrestler and wrestling trainer.
Hart had played football for the Edmonton Eskimos and been a champion wrestler, but was better known for his work behind the scenes in wrestling. In 1948 Hart founded Stampede Wrestling, a Calgary-based regional circuit. A number of top stars trained with Stu Hart, including Superstar Billy Graham, Abdullah The Butcher, Junkyard Dog, Brian Pillman, Chris Benoit and Chris Jericho.
In 1948 he married Helen Smith; she died in 2001. Together they had twelve children:
- Smith (1949-)
- Bruce (1950-)
- Keith (1951-)
- Wayne (1953-)

- Georgia (1956-)
- Bret (1957-)
- Allison (1959-)
- Ross (1961-)
- Diana (1963-), who was married to the wrestler British Bulldog Davey Boy Smith. She wrote a book entitled Under the Mat about life in the Hart family; it was removed from bookstores only weeks after its release in November 2001, following a lawsuit by Owen Hart's widow Martha over the contents.
