Philip Pusey (25 June 1799 – 9 July 1855) was a reforming agriculturalist, a Tory Member of Parliament (MP) and a friend and follower of Sir Robert Peel.
Pusey stood for election in Rye at a by-election in 1830 and was originally declared elected, but following an election petition he was unseated by an order of the House of Commons on 17 May 1830. He did not contest Rye at the 1830 general election, when he was elected as a Member for Chippenham. He did not contest Chippenham at the 1831 election, and stood instead in Rye. After riots in the town hall, Pusey agreed to withdraw from the election in return for a guarantee from General De Lacy Evans to protect the peace of the town; Evans won the seat.
Pusey was then returned at an uncontested by-election in July 1831 for the borough of Cashel in Ireland, and held that seat until the 1832 general election, when he stood unsuccessfully in Berkshire. He was elected without a contest from Berkshire at the 1835 general election, and held the seat until he retired from the House of Commons at the 1852 general election.
He was one of the founders of the Royal Agricultural Society, and was chairman of the agricultural implement section of the Great Exhibition of 1851. He was a fellow of the Royal Society, a writer on varied topics in the Journal of the Royal Agricultural Society and the author of the hymn Lord of our Life and God of our Salvation.
