Simon Luttrell, 1st Earl of Carhampton (c. 1713 – 14 January 1787) was an Anglo-Irish politician and peer who sat in the British House of Commons from 1754 to 1780.

He was the second son of Henry Luttrell, of Luttrellstown (whose family had held Luttrellstown since the land there had been granted to Sir Geoffrey de Luterel in about 1210 by King John of England) and his wife Elizabeth Jones.

He later received a pardon from the Williamite authorities and was accused by his former Jacobite comrades of having betrayed them.

Simon Luttrell served as a Member of Parliament in the House of Commons of Great Britain for four constituencies: Mitchell (1755–1761), Wigan (1761–1768), Weobley (1768–1774) and Stockbridge (1774–1780).

[1] On 22 January 1735, he married Judith Maria Lawes,[2] daughter of Sir Nicholas Lawes, Governor of Jamaica and Elizabeth Cotton (née Lawley), by whom he had eight children: Judith was the heir to a slave plantation owned by her father, which after the marriage came into Luttrell's ownership, and eventually passed into the control of his son.
