Matthew Quintal (1766 in Padstow (baptised 3 March 1766 as Mathew Quintril), Cornwall – 1799, Pitcairn Island) was a Cornish able seaman and mutineer aboard HMS Bounty. His surname was, in all probability, the result of misspelling the Cornish surname "Quintrell". He was the last of the mutineers to be murdered on Pitcairn Island. He was murdered by Ned Young and John Adams, leaving them the last two men alive on the island. Quintal's descendents reside on Norfolk Island to this day. A descendant, Malcolm Champion, was an Olympic swimmer.
