Palatinate or palatinate purple is a purple colour associated with Durham University and the County and City of Durham. The term has been used to refer to a number of different shades of purple. The Oxford English Dictionary defines it as a "light purple or lavender colour", which is used for Durham academic hoods. For corporate purposes Durham University uses a darker shade.

The academic dress of Durham University has many similarities with that of other older British universities such as Oxford and Cambridge. Most colleges of Durham University insist on gowns being worn on formal occasions, including matriculation and formal halls (dinners); exceptions are Van Mildert, St Cuthbert's Society, Collingwood, Stephenson, St Aidans, and The College of St Hild and St Bede. Some colleges also insist on their being worn to Junior Common Room meetings, and they are often seen in college chapels. At formal halls, only gowns are worn and doctors normally wear their undress gowns; for more ceremonial occasions full-dress gowns and hoods are worn by graduates. Until 1990, the General Regulations of university 'recommended' the wearing of gowns by members of the university when attending divine service at the Cathedral – but this is now left to individual choice apart from at certain services. Gowns are also customarily worn to meetings of the university Senate by members of that body.
