Salem Union Church and Cemetery, also known as Salem Lutheran Church and Salem United Church of Christ, is a historic United Church of Christ church and cemetery located near Maiden, Lincoln County, North Carolina. The church was built in 1849 as a simple rectangular brick building, and enlarged and remodeled in the Late Gothic Revival style in 1914–1915. With the remodeling, a two-stage corner tower was added and the window and door openings converted to lancet-arch openings. A two-story Sunday School addition was built in 1936–1937 and in 1989 a Fellowship Hall was built to form an H-shaped church building. Also on the property is a contributing well shed (c. 1928) and cemetery with burials dating to 1792. It was listed on the National Register of Historic Places in 1995.
