The University of Pittsburgh (Pitt) is a state-related research university in Pittsburgh, Pennsylvania, U.S. The university is composed of seventeen undergraduate and graduate schools and colleges at its urban Pittsburgh campus, home to the university's central administration and over 31,000 undergraduate and graduate students. The 132-acre Pittsburgh campus includes various historic buildings that are part of the Schenley Farms Historic District, most notably its 42-story Gothic revival centerpiece, the Cathedral of Learning. Pitt is a member of the Association of American Universities and is classified among "R1: Doctoral Universities – Very high research activity".

Pitt traces its roots to the Pittsburgh Academy founded by Hugh Henry Brackenridge in 1787. While the city was still on the edge of the American frontier at the time, Pittsburgh's rapid growth meant that a proper university was soon needed, and Pitt's charter was altered in 1819 to confer university status on it as the Western University of Pennsylvania. After surviving two fires and several relocations, the university moved to its current location in Pittsburgh's Oakland neighborhood, and by act of the state legislature was renamed the University of Pittsburgh in 1908. Pitt was a private institution until 1966, when it became part of the Commonwealth System of Higher Education.

The campus is situated adjacent to the flagship medical facilities of its closely affiliated University of Pittsburgh Medical Center (UPMC) and its flagship hospital, UPMC Presbyterian, as well as the Carnegie Museums of Pittsburgh, Schenley Park, and Carnegie Mellon University. The university also operates four undergraduate branch campuses in Western Pennsylvania, located in Bradford, Greensburg, Johnstown, and Titusville. In athletics, Pitt competes in Division I of the NCAA as the Pittsburgh Panthers, primarily as members of the Atlantic Coast Conference.
