St. Paul's Cathedral, Roman Catholic co-cathedral in downtown Saskatoon, Canada

St. Paul's Cathedral is a Roman Catholic co-cathedral in downtown Saskatoon situated where 22nd Street East meets Spadina Crescent. Built with Romanesque stone architecture, it overlooks the South Saskatchewan River with its substantial brick and stone exterior.

The cornerstone was placed in 1910 by Canadian Prime Minister Sir Wilfrid Laurier, and the building was consecrated the following year. The cathedral was constructed during a period when Saskatoon was expanding rapidly and needed new religious facilities.

The stained glass was documented by the Institute for Stained Glass in Canada. The windows were added in 1945 to commemorate parishioners who died in World War II, and renewed in 1976 after a fire damaged the church. The 1912 Casavant organ is another element visitors can see inside.

The co-cathedral stands at the corner of 22nd Street East and Spadina Crescent, on the west bank of the South Saskatchewan River in the Central Business District. Its small size means it no longer serves as the city's main cathedral; the Holy Family Cathedral, opened on 18 December 2011, took that role. Look for the two Imhoff paintings of Saints Peter and Paul in the sanctuary.

Two paintings of Saints Peter and Paul, originally from a closed church in Blaine Lake, were brought to the cathedral in 2019. These artworks connect the history of other religious sites in the region to this place.
