Newcome Cappe (21 February 1733 – 24 December 1800), was an English unitarian divine. He served as the pastor of the York Unitarian Chapel, located in York, England. Cappe published various sermons and after his death his second wife, Catharine Cappe published many more.
He was born at Leeds, West Yorkshire, the eldest son of the Rev. Joseph Cappe, minister of the nonconformist congregation at Mill Hill Chapel, Leeds, who married the daughter and coheiress of Mr. Newcome of Waddington, Lincolnshire. He was educated for the dissenting ministry. For a year (1748–49) he was with John Aikin at Kibworth, Leicestershire; then for three years he studied with Philip Doddridge at Northampton, East Midlands, and for another space of three years (1752–55) he lived in Glasgow, Scotland, profiting by the instruction of William Leechman.
Cappe was chosen in November 1755 as the co-pastor with the Rev. John Hotham of the York Unitarian Chapel at St. Saviourgate, York. After Hotham's death the following May, Cappe became the sole pastor to the congregation and remained in this position until his death. In 1788, when he was a widower with six grown-up children, he married Catherine Harrison (born 1744).
The writings of Cappe which appeared during his lifetime were minor. Among them were sermons preached on the days "of national humiliation" in 1776, 1780, 1781, 1782 and 1784. An earlier sermon delivered 27 November 1757, after the victory of Frederick the Great at the battle of Rossbach on 5 November 1757, was of a very rhetorical character and passed through numerous editions. In 1770, he published a sermon in memory of the Rev. Edward Sandercock, and in 1785, he published his sermons.
