United First Parish Church is a Unitarian Universalist congregation in Quincy, Massachusetts, established as the parish church of Quincy in 1639. The current building was constructed in 1828 by noted Boston stonecutter Abner Joy to designs by Alexander Parris. The building was designated a National Historic Landmark on December 30, 1970, for its association with the Adams family, who funded its construction and whose most significant members are interred here.
