Francis Aungier, 1st Earl of Longford PC was an English politician, who sat in the House of Commons from 1660 to 1679. He was an administrator in Ireland.
Aungier was the son of Ambrose Aungier, chancellor of St Patrick's Dublin, and his wife Grizzell Bulkeley, daughter of Lancelot Bulkeley. The Aungier family originated from Cambridgeshire, but his grandfather was appointed Master of the Rolls in Ireland. Aungier inherited the Barony on the death of his uncle Gerald Aungier, 2nd Baron Aungier of Longford in 1655.
