Christ Church, or Christ Episcopal Church, is an Anglican church in Winchester, Frederick County, Virginia. The church was founded in 1738, with its first vestry elected in 1742. It is the seat of Frederick Parish, Diocese of Virginia, which once covered half of the Shenandoah valley and western Virginia, including what became West Virginia. The current church building, the parish's third, was designed by Robert Mills (who also designed the Washington Monument and Monumental Church in Richmond, Virginia) - it was completed in 1828, and is the oldest church building continuously used for religious purposes in the county. It is a contributing building in the local Historic District which predates the National Register of Historic Places, and which has been expanded three times since 1980.
