Hiacoomes (~1610s – 1690) was a Wampanoag American Indian from the island of Martha's Vineyard, (Wampanoag: Noepe), who in 1643 became the first member of his society to convert to Christianity under the tutelage of the missionary Thomas Mayhew Jr. He would then, with the assistance of Mayhew, become a leading preacher to his fellow Wampanoag on the island, playing a major role in the widespread conversion of the Wampanoag from their traditional beliefs to Christianity.
