Thomas Middleton (1 March 1589 – c. 1662) of Horsham and Hangleton, Sussex was an English politician who sat in the House of Commons variously between 1640 and 1660.
Middleton was the son of John Middleton of Hill's Place, Horsham and his wife Frances Fowle, daughter of Nicholas Fowle of Rotherfield, Sussex.
Middleton attended Trinity College, Cambridge in 1606 and was a student of Inner Temple in 1607.
He was re-elected MP for Horsham in November 1640 for the Long Parliament[1] Middleton supported the Parliamentarian side, but in December 1643 he did not show any force against the Royalist troops in Sussex and was later charged with providing support to the Royalists.
He was absolved of the charges against him but was re-arrested in 1648 in connection with a rising that took place at Horsham that year.
