Eithan

Eithan is a spelling variant of Ethan, which comes from the Hebrew name אֵיתָן (Eitan), meaning firm, strong or enduring. Name dictionaries agree on this origin, and the same Hebrew word is used in the Psalms to convey strength and permanence. The E-i spelling is a modern English form rather than a distinct name with its own derivation.

It is pronounced EE-thuhn, identical in American and British English.

The best-known associations belong to the parent name. In the Hebrew Bible, Ethan the Ezrahite is counted among the wise men of Solomon’s court and is named in the heading of Psalm 89. In American history, Ethan Allen led the Green Mountain Boys during the Revolutionary War. The Israeli backstroke swimmer Eithan Urbach competed at two Olympics, set a national record in 1996 and shared Israel’s Sportsman of the Year award in 1997.

In the United States the spelling stayed uncommon for years: 59 boys received it in 2010, when it ranked 2,212. Growth since then has been steep, from 605 boys at rank 501 in 2022 to 3,636 boys at rank 97 in 2025. That is the name’s highest position on record and its first appearance in the top 100.
