The University of Manitoba Graduate Student's Association (GSA) is the student-run association for graduate students at the University of Manitoba. Each graduate student is automatically a fee-paying member of the association, and as such, the GSA represents graduate students from all disciplines. This diversity of representation is reflected on the Association's council, made up of many different department representatives. The University of Manitoba Graduate Student's Association (GSA) also operates a satellite office at the Bannatyne Campus (Health Sciences Graduate Student Association).

With over 3,000 members, the GSA is the official voice of graduate students to the Faculty of Graduate Studies, as well as to other levels of Administration at U of M. The GSA serves two dual purposes in providing its membership a wide variety of benefits and services: representation and advocacy on behalf of graduate student issues, and provision of services to its members, including travel grants, the Gradzette, and bursaries for students. Of the fees collected, some money is also allocated to department councils in the form of departmental grants.

The main office of the GSA is located on the Fort Garry campus, at 221 University Centre, however, the GSA is also active on the Bannatyne campus, where the Health Sciences GSA maintains an office and conducts council meetings and social activities.

The Graduate Students' Association exists to serve graduate students and is a powerful voice for graduate students at the University of Manitoba.
