An Affiliated College is an educational institution that operates independently, but also has a formal collaborative agreement with another, usually larger institution that may have some level of control or influence over its academic policies, standards or programs.

While a university may have one or several affiliated colleges, it is not necessarily a collegiate university, which is a union or federation of semi-autonomous colleges. For the most part, this model is restricted to colleges and universities. On rarer occasions, however, elementary schools or high schools may also enter into affiliating agreements.
