Riley is a unisex given name of English and Irish origin, derived from two distinct surnames. As an English surname, it originates from Old English ryge (rye) and lēah (wood, clearing), meaning "rye clearing." As an Irish surname, it is a variant of Reilly, itself an Anglicized form of the Irish Ó Raghallaigh, derived from the personal name Raghallach of unknown meaning. Historical Usage Before 1980, Riley was an uncommon masculine name in the United States. During the 1980s and 1990s, it steadily increased in popularity for both boys and girls, and from 2003 onwards it has been more common for girls in the United States.
