Reilleah is Irish in Origin.

Reilleah is a modern, rare feminine given name in English-speaking contexts, likely a creative fusion of the Irish/English Riley/Reilly and the biblical Leah. Its first element recalls the Irish surname Ó Raghallaigh (anglicized Reilly) as well as the English place-name Riley from Old English ryge + lēah, “rye clearing” or “meadow.” The second element comes from Hebrew Le’ah, long borne in the Hebrew Bible by Jacob’s wife. Common pronunciations include RYE-lee-uh and ree-LEE-uh.

Because it is a contemporary coinage, Reilleah has no single traditional meaning; families often read it as combining the pastoral “meadow” sense of Riley with Leah’s enduring biblical resonance. Variant spellings include Reileah, Reileigh, Reilea, Reillia, and Raeleah; related names are Riley, Rylee, Reilly, and Leah. Usage to date remains uncommon but rising in creative naming trends. Possible nicknames are Rei/Ray, Ria, and Leah.
