Toronto Metropolitan University (TMU, or Toronto Met), formerly known as Ryerson University, is a public research university located in Toronto, Canada. The university's core campus is situated within the Garden District in downtown Toronto, although it also operates facilities elsewhere in the city. The university includes nine academic divisions/faculties: the Faculty of Arts, the Faculty of Community Services, the Faculty of Engineering and Architectural Science, the Faculty of Science, The Creative School, the Lincoln Alexander School of Law, the Ted Rogers School of Management, the School of Medicine, and the Yeates School of Graduate and Postdoctoral Studies. Many of these are further organized into smaller departments and schools. The university also provides continuing education services through the Chang School of Continuing Education.

The institution was established in 1948 as the Ryerson Institute of Technology, named after Egerton Ryerson, a prominent contributor to the design of the public school system and teachers' college in Canada West. In 1964, the institution was reorganized under provincial legislation and renamed Ryerson Polytechnical Institute. Under that name, it was granted limited degree-granting powers during the 1970s. The institution was reorganized into a full-fledged university in 1993 and renamed Ryerson Polytechnic University. In 2002, several years after the university's school of graduate studies was established, the university adopted the name Ryerson University. In 2022, it was renamed Toronto Metropolitan University, in response to concerns about Egerton Ryerson's influence on the Canadian Indian residential school system.

The university is a co-educational institution, with approximately 44,400 undergraduates and 2,950 graduate students enrolled there during the 2019–20 academic year. As of 2024, TMU has over 240,000 alumni. The university's athletics department operates several varsity teams that play as TMU Bold, competing in the Ontario University Athletics conference of U Sports.
