All Saints’ Cathedral is a historic Episcopal cathedral in Milwaukee, Wisconsin. The cathedral as an ecclesiastical entity dates from 1867, when Jackson Kemper, the first bishop of Wisconsin, and his coadjutor William Armitage, were deeded the assets of a small church in downtown Milwaukee and renamed it "All Saints’ Pro-Cathedral." The cathedral moved to its present campus on Juneau Avenue in 1868, buying a wooden boarding house at one end of the block, then, in 1872, purchasing a church building at the other end when it came up for sale.

All Saints' was the "see," or seat, of the Bishop of Wisconsin until 1886; from then until 2023, it was the bishopric seat of the Diocese of Milwaukee. With the 2024 merger of the Milwaukee diocese with those of Fond du Lac and Eau Claire, All Saints' is again a historic cathedral parish within the Episcopal Diocese of Wisconsin.

The church reported 238 members in 2017 and 136 members in 2023; no membership statistics were reported in 2024 parochial reports. Plate and pledge income reported for the congregation in 2024 was $198,228 with average Sunday attendance (ASA) of 68 persons.
