The Association of University of New Brunswick Teachers (AUNBT) is the trade union representing the full-time and part-time professors, instructors, and academic librarians at the University of New Brunswick in the province of New Brunswick, Canada. Established in 1956 as a faculty association, AUNBT joined the Canadian Association of University Teachers (CAUT) that same year. In 1979 the organization was certified by the Industrial Relations Board as the bargaining agent for full-time academic staff, both faculty and librarians, at the two principal campuses of UNB. The first collective agreement came into effect in 1980.
