Elliott, with two t's, is a spelling of the English surname Elliot, which grew out of Elias, the Greek form of Elijah, and means "my God is Yahweh". The double-t version is the one used for the boy in Spielberg's E.T. and feels a touch more formal to many parents. Elliott ranked 539th in the United States in 2000, peaked at number 158 in 2020 and has held steady in the 160s since, standing at number 160 in 2025.
