Sea Venture was a seventeenth-century English sailing ship, part of the Third Supply mission to the Jamestown Colony, that was wrecked in Bermuda in 1609. She was the 300 ton purpose-built flagship of the London Company and a highly unusual vessel for her day, given that she was the first single timbered merchantman built in England, and also the first dedicated emigration ship. Sea Venture's wreck is widely thought to have been the inspiration for William Shakespeare's play The Tempest.
