Grey College is a college of Durham University in England, founded in 1959 as part of the university's expansion of its student population. The college was originally planned to be named Oliver Cromwell College, but this proved too controversial. Instead, the college is named after Charles Grey, 2nd Earl Grey, who was Prime Minister of the United Kingdom at the time of the university's foundation.

The Colleges of Durham University are residential colleges that are the primary source of accommodation and support services for undergraduates and postgraduates at Durham University, as well as providing a focus for social, cultural and sporting life for their members, and offering bursaries and scholarships to students. They also provide funding and/or accommodation for some of the research posts in the University. All students at the University are required to be members of one of the colleges.
