Sir Thomas Trevor (6 July 1586 – 21 December 1656) was an English lawyer, judge and Member of Parliament, most notable for having delivered the judgment against John Hampden in the Ship Money case.
[2] In 1619 he was knighted and appointed solicitor to Prince Charles; the following year, he was a reader of his inn, and he sat as MP for Saltash in the Parliaments of 1621 and 1624–5, and for East Looe in that of 1625.
At the conclusion of the impeachment in 1643, he was found guilty, fined and sentenced to be imprisoned at the pleasure of the House of Lords, but he was released immediately and resumed his seat on the bench.
At Michaelmas 1643, when the King sent a writ demanding the attendance of him and another judge (Edmund Reeve) on the court at Oxford, they refused and had the messengers arrested: one was later executed as a spy.
By the former he had an only son Thomas, who was created a baronet in 1641, and died without issue on 26 February 1676, when his estate descended to Sir Charles Wheler, grandson of Trevor's sister Mary.
