Meaning and history
Eithan is a modern variant of Ethan and the Hebrew Eitan, derived from a Hebrew word meaning solid, enduring or firm. The root appears in the Old Testament in the name of several minor figures, including Ethan the Ezrahite, traditionally associated with Psalm 89. A notable bearer of this spelling is Israeli Olympic swimmer Eithan Urbach.
Eithan rose from #226 to #97 for boys between 2024 and 2025. That year also produced its highest recorded birth count, at 3,636.
