St. Mary's Cathedral (or its full name Cathedral of Saint Mary of the Immaculate Conception) in Kingston, Ontario, Canada is a Roman Catholic cathedral. It is one of four churches located within 600m along Clergy Street (the other three are Chalmers United Church, St. Andrew's Presbyterian Church, and Queen Street United Church).

Designed by architect James R. Bowes, construction began in 1842. The cathedral was officially opened October 4, 1848. It was greatly enlarged in 1889 with a design by Joseph Connolly.  

Coming up to the 175th Anniversary, St. Mary’s will be looking to invite the community into this beautiful space to see, hear, understand and reflect in our history and family.
