The University of Toronto Mississauga (UTM or U of T Mississauga) is one of the three campuses of the University of Toronto and its second-largest academic division, located in Mississauga, Ontario, Canada.

Established in 1967 as Erindale College, the suburban campus is set upon 225 acres of protected forest along the valley of the Credit River, approximately 33 kilometres west of the St. George campus in downtown Toronto.

Originally a constituent college in the Faculty of Arts and Science, UTM became a full academic division of the University of Toronto in 2003. The campus has since grown to become the university's second-largest division overall and its second-largest campus in terms of both student enrolment and land area, the other two of which are its St. George and Scarborough campuses.

UTM hosts more than 180 programs at both the undergraduate and graduate level, offered through 15 academic departments, three institutions, and several other University of Toronto faculties, including the Temerty Faculty of Medicine and Lawrence Bloomberg Faculty of Nursing. The campus mainly provides undergraduate education in arts and science, similar to the Faculty of Arts and Science on the St. George campus, as part of the university's tri-campus structure. UTM also offers graduate programs, notably in the Mississauga Academy of Medicine, one of the four academies in the Temerty Faculty of Medicine's MD program, and the Institute for Management and Innovation.
