United First Parish Church is an American Unitarian Universalist congregation in Quincy, Massachusetts, established as the parish church of Quincy in 1639. The current building was constructed in 1828 by Boston stonecutter Abner Joy to designs by Alexander Parris. It was designated a National Historic Landmark on December 30, 1970, for its association with the Adams family, who funded its construction; four members of the family are buried there.
