St. Mary's Orthodox Church (West Virginia)

St. Mary's Orthodox Church, originally known as Nativity of the Most Holy Mother of God Russian Orthodox Church, is a historic church of the American Carpatho-Russian Orthodox Diocese located at the intersection of West Park and Holland Avenues in Westover, Monongalia County, West Virginia. It was also known as St. Michael the Archangel Church and St. Mary's Capatho-Russian Orthodox Greek Catholic Church.

The building itself was built in the 19th century and originally housed the Westover Methodist Church. It was later sold to the Orthodox Church, at which time it underwent significant alterations to bring it to the architectural standards necessary for an Orthodox house of worship. It was dedicated as an Orthodox church on September 8, 1923 (hence its dedication to the Nativity of the Virgin Mary, which feast day falls on that date). It is a yellow brick building on a high foundation of textured concrete block.

It was listed on the National Register of Historic Places in 1988.
