St. Michael's Church is a historic Episcopal church at 225 West 99th Street and Amsterdam Avenue on Manhattan's Upper West Side in New York City. The parish was founded on the present site in January 1807, at that time in the rural Bloomingdale District. The present limestone Romanesque building, the third on the site, was built in 1890–91 to designs by Robert W. Gibson and added to the National Register of Historic Places in 1996.

Robert W. Gibson, AIA, was an English-born American ecclesiastical architect active in late-nineteenth- and early-twentieth-century New York state. He designed several large Manhattan churches and a number of prominent residences and institutional buildings.
