Clark's Island is the name of a small island located in Duxbury Bay in the U.S. state of Massachusetts.[1] It was named for John Clark, the first mate of the Mayflower, the ship that brought the Pilgrims to New England.[2] The island was initially considered for the location of the Pilgrim's settlement, but was rejected in favor of a site to the south, which became known as Plymouth, Massachusetts.[3] Today Clark's Island is a part of the town of Plymouth.[1]
