Dalhousie University is a university located in Halifax, Nova Scotia, Canada.

As the largest post-secondary educational institution in the Maritime Provinces it offers a wide array of programmes, including a Medical Programme and the Dalhousie Law School. The chancellor is Dr. Richard Goldbloom; Dr. Tom Traves serves as president and vice-chancellor.

Dalhousie College was founded in 1818 by George Ramsay, 9th Earl of Dalhousie, the Lieutenant-Governor of Nova Scotia. In 1920 the University of King's College in Windsor, Nova Scotia, English Canada's oldest degree granting institution, burned down. Through a grant from the Carnegie Foundation, King's College was able to relocate to Halifax and entered into a partnership with Dalhousie University. While often seen as a separate but integrated institution it shares Dalhousie's Arts and Sciences Faculty, but offers several interdisciplinary humanities degree programmes, such as Contemporary Studies, History of Science and Technology and Early Modern Studies.

Following a period of government-mandated consolidation of post-secondary institutions during the 1990s, the Technical University of Nova Scotia was merged with Dalhousie University in 1997. It was initially known as Dalhousie University Polytechnic, or DalTech, but in 2000 the DalTech nickname was dropped and the engineering, architecture and computer science faculties of TUNS are fully integrated into Dalhousie University. The Faculty of Engineering and the Faculty of Architecture and Planning are located on the Sexton Campus, east of the Carleton Campus and closer to downtown Halifax. The Faculty of Computer Science moved to its own building on Studley Campus in 1999.
