Peter Perchard (c. 1729 – 21 January 1806) was a British goldsmith and merchant who served as Lord Mayor of London in 1804. Perchard worked as a merchant on his native island of Guernsey and the other Channel Islands. Perchard grew wealthy from privateering in the English Channel after the British government declared reprisals against the allies of the nascent United States of America. Perchard and his fellow privateers targeted ships from the French West Indies, with Perchard personally making almost £10,000 from his privateering activities.
