The Centre for Transnational Mennonite Studies (CTMS) is a research centre at the University of Winnipeg that approaches the history and culture of Mennonites within a transnational context. It recognizes that Mennonites are a global people, historically engaging as settlers in international migrations, multi-national residences, international social services, and foreign missions amidst a strengthening dialogue between communities of the Global North and South. CTMS seeks to enhance teaching, research, knowledge mobilization, and community outreach by employing a transnational framework.

CTMS was established in 2016 as a partnership between the Chair in Mennonite Studies (since 1978) and the community-based D.F. Plett Historical Research Foundation Inc. (located at the University of Winnipeg since 2005).
