St. Mary's Parish Hall is a historic sandstone building in the Mission District of Calgary.
It was built in 1905 to be used as a Roman Catholic parish hall, but starting in 1913 was adaptively reused as a railway station by the Canadian Northern Railway (CNoR), during which time it was known as Calgary Southwest Railway Station.
In 1981 the building was named a Provincial Historic Resource of Alberta.
In 1985 a fire gutted most of the interior and it was restored in 1987.
