St. Joseph's Catholic Mission Church is a site on the National Register of Historic Places located in Townsend, Montana.

According to its NRHP nomination, it is "the oldest extant example of secular Roman Catholic church architecture in Montana.

The addition of a belfry and steeple in 1902 somewhat altered the church's Colonial appearance, but still carried forward its earlier design features.

"[2] The church building was moved to its current location in 1954 by the U.S. Bureau of Reclamation in order to save it from demolition.
