Alexander Luttrell (10 May 1705 – 4 June 1737) of Dunster Castle, Somerset, was an English politician and land-owner who served as Member of Parliament for his family's pocket borough of Minehead from 1727 until his death.

[1][2][3] On 18 April 1724 he married Margaret Trevelyan at St Anne, Soho, London, Westminster, England,[4] daughter of Sir John Trevelyan, 2nd Baronet of Nettlecombe, Somerset, by whom he had a daughter and sole heiress Margaret Luttrell.

The Luttrell family's ownership of the manor and castle of Dunster gave them a "natural interest" over the seat of Minehead, thus a Pocket Borough, and he was returned as a Tory Member of Parliament for that borough shortly after coming of age.

Fownes served as Member of Parliament for the Luttrell family's pocket borough of Minehead.

[9] Several portraits of Alexander Luttrell are listed by Maxwell Lyte (1909), but there is some difficulty in identifying him due to his similar appearance to his brother Francis.
