Thomas Thynne was an English landowner of the family that is now headed by the Marquess of Bath and politician who sat in the House of Commons from 1670 to 1682. He went by the nickname "Tom of Ten Thousand" due to his great wealth. He was a friend of the Duke of Monmouth, a relationship referred to in John Dryden's satirical work Absalom and Achitophel where Thynne is described as "Issachar, his wealthy western friend".

Sir Thomas Thynne (c.1578–1639), of Longleat, Wiltshire, was an English landowner and politician who sat in the House of Commons at various times between 1601 and 1629. His romance with the daughter of his family's enemies may have inspired Shakespeare to pen Romeo and Juliet.
