Walter Clarke (1640–1714) was an early governor of the Colony of Rhode Island and Providence Plantations and the first native-born governor of the colony. The son of colonial President Jeremy Clarke, he was a Quaker like his father. His mother was Frances (Latham) Clarke, who is often called "the Mother of Governors." While in his late 20s, he was elected as a deputy from Newport, and in 1673 was elected to his first of three consecutive terms as assistant. During King Philip's War, he was elected to his first term as governor of the colony. He served for one year in this role, dealing with the devastation of the war, and with the predatory demands of neighboring colonies on Rhode Island territory during the aftermath of the war.
