Alias is a modern pick that most parents treat as a fresh spelling of Elias, the Greek form of Elijah, which means "my God is Yahweh"; it also matches the English word alias, from the Latin for "otherwise". The spelling with a connects it to Atlas and Amias, two other rising a-names. Alias climbed from number 3424 in 2000 to number 1572 among US boys' names in 2025, its best rank so far.
