The Concordia University Alumni Association (CUAA) was created in 1983. In the words of its constitution, the association exists to "encourage the fellowship of graduates from Loyola, Sir George Williams, and Concordia University through social, educational and cultural activities" and to "preserve and promote the interests of Concordia University through alumni involvement in its future and governance." All graduates of the University are automatically lifetime members of CUAA, as are graduates of Concordia's two founding institutions: Loyola College and Sir George Williams University, which merged in 1974 to form Concordia University. CUAA worked with Concordia's Office of Alumni Affairs to provide alumni with a variety of programs and services. It organizes a series of career and personal development seminars and workshops, and a travel program; all are outlined in the calendar of events mailed to Montreal-area graduates. All graduates receive the quarterly Concordia University Magazine. CUAA is committed to the development and support of a worldwide network of alumni chapters.

On June 8, 2001, CUAA president Peter McAuslan and Rector Frederick Lowy signed a memorandum of understanding (MOU) between the CUAA and Concordia. The MOU was “for the purpose of delineating the responsibilities of the University and the CUAA to each other for their mutual benefit.” Among other details, the agreement spells out the support that Concordia is to provide the association in the form of funding, services and personnel, and the financial commitment that the CUAA pledges in return, as well as the continuing place of the alumni associations of Loyola and Sir George.

In 2014, the Concordia University Alumni Association, Association of Alumni of Sir George Williams University and Loyola Alumni Association have united. On May 28, at special general meetings, the associations unanimously approved amalgamating into one organization.
