Trinity College is the oldest residential college of the University of Melbourne, the first university in the colony of Victoria, Australia. The college was opened in 1872 on a site granted to the Church of England by the government of Victoria. In addition to its resident community of 380 students, mostly attending the University of Melbourne, Trinity's programs includes the Trinity College Theological School, an Anglican training college which is a constituent college of the University of Divinity; and the Pathways School which runs Trinity College Foundation Studies and prepares international students for admission to the University of Melbourne and other Australian tertiary institutions, as well as summer and winter schools for young leaders and other short courses.

Sir John Clifford Valentine Behan, the first Rhodes Scholar from the state of Victoria, was an Australian educationalist and lawyer, the second warden of Trinity College at the University of Melbourne, and "beyond the college life [at Trinity,] he was a sound and far-seeing secretary in Australia of the Rhodes Scholarship Trust for 30 years from 1922 to 1952".
