Thomas Tichborne (1567 – 20 April 1602) was an English Roman Catholic priest.

Born at Hartley Mauditt, Hampshire, in 1567, Thomas was a younger son of Nicholas Tichborne and Mary Myll.

[2] He was sent a prisoner to the Gatehouse in London, but in the autumn of 1598 was helped to escape by his brother, Nicholas Tichborne, and Thomas Hackshott, who were both executed shortly afterwards.

Betrayed by Atkinson, an apostate priest, he was re-arrested and on 17 April 1602, was brought to trial with Robert Watkinson (a young Yorkshire man who had been educated at Rome and ordained priest at Douai a month before) and James Duckett, a London bookseller.

He had been ordained at Douai in 1600 and received into the Society of Jesus while a prisoner in Newgate.
