Union College, University of Queensland, Heritage residential college at University of Queensland in St Lucia, Australia.

Union College is a residential college at the University of Queensland comprising three-story blocks arranged to create interior courtyards with planted trees and stone perimeter walls. The buildings connect through these shared outdoor spaces that sit between the main structures.

Designed by James Birrell in 1964, the college was the first co-educational residential facility at the university established without religious affiliation or restrictions. This approach marked a departure from earlier residential models and expanded access to student housing.

Union College was planned in 1943 by the University of Queensland Students' Union as a non-denominational alternative to the religious colleges, and it was run by a Warden elected by the students and approved by the Senate. It opened as a student hostel in rented premises on Wickham Terrace in 1947, gained college status by 1950, and only moved to its St Lucia building later.

The college provides accommodation with daily meals, cleaning services, and study facilities included in the residential package. As an active residential community, access to buildings and grounds is best arranged through scheduled visits rather than casual drop-in access.

The residential blocks sit elevated on concrete supports with large pivoting windows designed for natural air flow and views toward the Brisbane River. This raised design anticipated flooding concerns while creating open space underneath the buildings.
