Kelley is Irish in Origin.

Kelley is an Anglicized Irish surname and given name derived from Ó Ceallaigh, meaning “descendant of Ceallach.” The personal name Ceallach is of early Irish origin with debated etymology; scholars variously connect it to cellach “war/strife, warrior” or to ceall “church,” suggesting “church-associated.” As a result, Kelley is often glossed as “warrior” or “bright-headed” in older sources, though “descendant of Ceallach” remains the most precise.

As a forename in the English-speaking world, Kelley developed from the prominent Irish surname, borne by multiple medieval dynasties (notably the Uí Ceallaigh of Connacht). In the 20th century it gained use for boys and, more strongly, for girls, following the surge of the simpler spelling Kelly; Kelley remains the traditional alternative and a common family-name spelling. Variants include Kelly, Kellie, Kelli, Kellee, and O’Kelly as a related surname form; Gaelic forms include Ó Ceallaigh and Ní Cheallaigh.
