The Cathedral Church of All Saints is the bishop's church of the Episcopal Diocese of Milwaukee, in Milwaukee, Wisconsin, USA. The current parish is a descendant of a small mission by the Right Reverend Jackson Kemper. It is located in Milwaukee's downtown Yankee Hill neighborhood. The complex was listed on the National Register of Historic Places in 1974. Most of the stained glass windows in the cathedral were designed and produced in England, most by Lavers, Barraud and Westlake of London. A large rondel window of Christ the King was made by Heaton, Butler and Bayne, also of London.
