The Ontario Tech Ridgebacks are the athletic teams that represent Ontario Tech University in Oshawa, Ontario, Canada. The Ridgebacks have been competing in Ontario University Athletics since 2006 and have been a member of U Sports since 2008.

Ontario University Athletics is a regional membership association for Canadian universities which assists in co-ordinating competition between their university level athletic programs and providing contact information, schedules, results, and releases about those programs and events to the public and the media. This is similar to what would be called a college athletic conference in the United States. OUA, which covers Ontario, is one of four such bodies that are members of the country's governing body for university athletics, U Sports. The other three regional associations coordinating university-level sports in Canada are Atlantic University Sport (AUS), the Canada West Universities Athletic Association (CW), and Réseau du sport étudiant du Québec (RSEQ).
