Trinity Church Complex is a historic church off of Northern Boulevard in Roslyn, New York. It is located on the westbound off-ramp from the Roslyn Viaduct and Church Street, the latter of which also leads to the St. Mary's Church Roman Catholic Church of Roslyn, on the northeast corner of Bryant and Summit Avenues. It was built in 1906 by the architectural firm of McKim, Mead & White, and also includes the 1951-established Roslyn-Trinity Cooperative Day School. The church complex was added to the National Register of Historic Places in 1986.
