St Anthony or Santo António was a Portuguese carrack that foundered in Gunwalloe Bay, Cornwall, in 1527 en route from Lisbon to Antwerp. She had a mixed cargo including copper and silver ingots. The wreck was recorded historically, because the salvage of the cargo was the subject of an international dispute that led to a Court of Star Chamber, but the location of the wreck was unknown until 1981. The wreck is designated under the Protection of Wrecks Act and is managed by Historic England.
