Dalhousie University (commonly known as Dalhousie or Dal) is a public research university in Nova Scotia, Canada, with three campuses in Halifax, and a fourth in Bible Hill. Dalhousie offers more than 4,000 courses and 180 degree programs in twelve undergraduate, graduate, and professional faculties.  The university is a member of the U15, a group of research-intensive universities in Canada.
Dalhousie was established as a nonsectarian college in 1818 by the Lieutenant Governor of Nova Scotia, George Ramsay, 9th Earl of Dalhousie, after whom the university was named. The college did not hold its first class until 1838, until then operating sporadically due to financial difficulties. It reopened for a third time in 1863 following a reorganization which brought a change of name to "The Governors of Dalhousie College and University". The university had formally changed its name to "Dalhousie University" in 1997 through provincial legislation, the same legislation which had merged the institution with the Technical University of Nova Scotia.
The Dalhousie library system currently operates the largest library in Atlantic Canada, as well as holds the largest collection of agricultural resource material in the region. The university operates a total of fourteen residences. There are currently two student unions that represent student interests at the university, the Dalhousie Student Union, and the Dalhousie Association for Graduate Students. Dalhousie's varsity teams, the Tigers, compete in the Atlantic University Sport conference of Canadian Interuniversity Sport. Dalhousie’s Faculty of Agriculture varsity teams are the Dalhousie Rams, and compete in the ACAA and CCAA.
