William Strachey was an English writer whose works are among the primary sources for the early history of the English colonisation of North America. He is best remembered today as the eye-witness reporter of the 1609 shipwreck on the uninhabited island of Bermuda of the colonial ship Sea Venture, which was caught in a hurricane while sailing to Virginia. The survivors eventually reached Virginia after building two small ships during the ten months they spent on the island. His account of the incident and of the Virginia colony is thought by most Shakespearean scholars to have been a source for Shakespeare's play The Tempest.

Sea Venture was a seventeenth-century English sailing ship, part of the Third Supply mission flotilla to the Jamestown Colony in 1609. She was the 300 ton flagship of the London Company. During the voyage to Virginia, Sea Venture encountered a tropical storm and was wrecked, with her crew and passengers landing on the uninhabited Bermuda. Sea Venture's wreck is widely thought to have been the inspiration for William Shakespeare's 1611 play The Tempest.
