St Anne's Cathedral, also known as Belfast Cathedral, is a cathedral of the Church of Ireland in Donegall Street, Belfast, Northern Ireland. It is unusual in serving two separate dioceses (Connor and Down and Dromore), yet being the seat of neither (it is geographically in the Diocese of Connor), it is therefore not a cathedral in the truest sense of the word, a cathedral being a church housing the seat of a bishop. It is, however, titled as such. It is the focal point of the Cathedral Quarter, Belfast.
