Thomas Papillon (1623 – 1702) was an English merchant and politician who was an influential figure in London. His candidacy for shrievalty (sheriff) of London in 1682 resulted in a legal battle with Sir William Pritchard (1632 -1705), in which he was ordered to pay £10,000. To avoid payment, he mortgaged his estates to his son-in-law and fled to Utrecht.
