John Fownes Luttrell (1752 – 16 February 1816) was an English Tory politician from Dunster Castle in Somerset. Like many previous generations of Luttrells since the 16th century, he was a Member of Parliament (MP) for Minehead, his family's pocket borough near Dunster. He sat in the House of Commons of Great Britain and then in the House of Commons of the United Kingdom from 1774 until his death, except for a few months in 1806–07.
Fownes Luttrell was the oldest son of Henry Fownes Luttrell I (formerly Henry Fownes, c. 1722–1780). His mother Margaret was the daughter of Alexander Luttrell (1705–1737), who had bequeathed his estates to Margaret on condition that her husband take the surname Luttrell.
in 1782 Fownes Luttrell married Mary Drewe, daughter of Francis Drewe of The Grange, Devon. They had 5 sons and four daughters, including:
At the 1774 general election, Fownes Luttrell was elected as one of the two Members of Parliament (MPs) for Minehead, his family's pocket borough. The borough's second seat was held by his father, who had secured Lord North's support for unopposed Luttrell patronage of the borough with an expectation that one candidate would be a North nominee. Henry Fownes Luttrell therefore promptly vacated his seat in favour of North's candidate, former Governor Thomas Pownall.
