Meaning & Origin
A female given name originating as a coinage.
Kaleigh is a girl's and boy's baby name, a variant spelling of Kaylee, of Irish origin, from the Gaelic caol, meaning 'slender' — or possibly from Caoilfhinn, 'slender and fair.' With over 16,000 recorded births in U.S. SSA data, it has considerable American history.
The Kaylee sound has been one of the most popular in American girls' naming for decades, and Kaleigh's spelling adds an Irish-heritage visual element to the beloved name. Its "-eigh" ending gives it an antiquated English spelling convention that paradoxically feels fresh — the same trick that makes names like Leigh and Sleigh feel distinctive.
