The University of Connecticut (UConn) is a public land-grant research university system with its main campus in Storrs, Connecticut, United States. It was founded in 1881 as the Storrs Agricultural School, named after two benefactors. In 1893, the school became a public land grant college, then took its current name in 1939. Over the following decade, social work, nursing, and graduate programs were established. During the 1960s, UConn Health was established for new medical and dental schools. UConn is accredited by the New England Commission of Higher Education.

With more than 32,000 students, the University of Connecticut is the largest university in Connecticut by enrollment. The university is classified among "R1: Doctoral Universities – Very high research activity". UConn is one of the founding institutions of the Hartford-Springfield regional economic and cultural partnership alliance known as New England's Knowledge Corridor. UConn was the second U.S. university invited into Universitas 21, an international network of research-intensive universities.

The school's athletic teams compete in the Big East Conference as the Huskies.
