The University of Exeter is a public research university in Exeter, Devon, South West England, United Kingdom. Its predecessor institutions, St Luke's College, Exeter School of Science, Exeter School of Art, and the Camborne School of Mines were established in 1838, 1855, 1863, and 1888 respectively. These institutions later formed the University of Exeter after receiving its royal charter in 1955. In post-nominals, the University of Exeter is abbreviated as Exon. (from the Latin Exoniensis), and is the suffix given to honorary and academic degrees from the university.

The university has four campuses: Streatham and St Luke's (both of which are in Exeter); and Truro and Penryn (both of which are in Cornwall). The university is primarily located in the city of Exeter, Devon, where it is the principal higher education institution. Streatham is the largest campus containing many of the university's administrative buildings. The Penryn campus is maintained in conjunction with Falmouth University under the Combined Universities in Cornwall (CUC) initiative. The Exeter Streatham Campus Library holds more than 1.2 million physical library resources, including historical journals and special collections. The annual income of the institution for 2020–21 was £503.1 million of which £94.6 million was from research grants and contracts, with an expenditure of £512.8 million.
