- Irish: Brave; originally a boys'' name, Riley has become increasingly popular as a name for girls.
Riley first became popular as a given name for boys but began establishing itself as a girl's name in 1990. The surname, which is derived from Ó Raghallaigh and O'Reilly in Ireland, is also an English place name meaning "rye field" or "rye clearing." The total number of female Rileys has outnumbered the total of male Rileys since the early 2000s, which probably means this fun-sounding name will become more a girls name as the years go on, as unisex names are apt to do.
