Peter Nourse (October 10, 1774 – March 25, 1840) was an American clergyman and librarian.

Caleb Barnum of Taunton, moved to Ellsworth, Maine, where, 9 September 1812, he was ordained over the newly established Congregational church.

[1][2] According to Ellsworth church historian Wayne Smith, his "Unitarian, or at least 'liberal', leanings eventually created some controversy among his parishioners", resulting in a decline in membership.

[2] His wife had died previously to this, and, as he had no children, he went to live, first with his brother, Dr. Amos Nourse, at Bath, and then with his nephew, Dr. Thomas Childs, at Phippsburg, Maine.
