The Cathedral Church of Saint Philip is a Church of England cathedral and the seat of the Bishop of Birmingham. Built as a parish church in the Baroque style by Thomas Archer, it was consecrated in 1715. Located on Colmore Row in central Birmingham, St Philip's became the cathedral of the newly formed Diocese of Birmingham in 1905. The cathedral is a Grade I listed building.

Thomas Archer (1668–1743) was an English Baroque architect. His buildings are important as the only ones by an English Baroque architect to show evidence of study of contemporary continental, namely Italian, architecture.
