Minor Island is a small, low island in the Strait of Juan de Fuca, near Smith Island seven miles west of Whidbey Island in western Island County. At low tide the island is connected with Smith Island by a rocky ridge. It was named by U.S. Coast Survey in 1854. The name chosen was for the minor value and appearance of the islet. In 1791, Lieut. Francisco de Eliza called it together with Smith Island, Islas de Bonilla.
