Mariners' Church of Detroit is a church with worship services adhering to Anglican liturgical traditions located at 170 East Jefferson Avenue in Downtown Detroit. It was founded in 1842 as a special mission to the maritime travelers of the Great Lakes and functioned as a parish of the Episcopal Diocese of Michigan until 1992, when the Michigan Court of Appeals ruled it was incorporated as an independent congregation. The church was listed on the National Register of Historic Places in 1971. The church has a non-exclusive, limited association with the REC Diocese of Mid-America which itself is a founding member of the Anglican Church in North America.
