St Cuthbert's Society, colloquially known as Cuth's, is a college of Durham University. It was founded in 1888 for students who were not attached to the existing colleges. St Cuthbert's Society is a Bailey college, based on Durham's peninsula next to the River Wear, although it also has other accommodation a few minutes' walk away in Old Elvet.

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.
