The Belleville Dutch Reformed Church, listed on the National Register of Historic Places as Reformed Dutch Church of Second River, is a historic church located in Belleville, Essex County, New Jersey, United States. Founded as a Dutch Reformed church in 1697, it is named after the Second River, which is a tributary of the Passaic River. The church was rebuilt in 1725 and again in 1807. The church steeple was used as an observation post during the American Revolution.[2] Over 62 Revolutionary soldiers are buried in the adjacent graveyard. The current church building was built in 1853.[3]
