St. Mary's Cathedral in Calgary, Alberta, Canada is a Roman Catholic cathedral. The building’s full name is The Cathedral of the Immaculate Conception of the Blessed Virgin Mary.

St. Mary’s began as a sandstone church in 1889, built near the Elbow River on land provided by the Canadian Pacific Railway. The area was called the Mission District, due to the settlement of Father Albert Lacombe in the area in 1884. The original Catholic mission was called Notre-Dame-de-la-Paix. The land was used to establish a French-speaking incorporated village called Rouleauville, which subsequently became overwhelmingly English and was annexed by Calgary in 1907 (making St. Mary's part of Calgary). The same land obtained by Lacombe was also used to build St. Mary's School nearby.

When Pope Pius X created the Diocese of Calgary November 30, 1912, St. Mary’s became the Cathedral as the seat of the Bishop.

Demolition of the sandstone cathedral began on July 21, 1955, and on October 30, 1955, the cornerstone for the Cathedral was laid. Construction completed in February 1957, and the Most Reverend Francis P. Carroll, Bishop of Calgary, consecrated the sanctuary December 11, 1957.

The cathedral is built of brick with sandstone accents in a modern gothic style. The floor plan is a St. Anthony's Cross (T or Tau-shaped) rather than the usual Latin cross that forms most Western Christian churches.

The tabernacle, chalices, monstrance, candle holders and sanctuary lamp were all designed and cast by Gunning and Son Bronze Works of Dublin.
