Reiley is Irish in Origin.
Reiley blends Irish and English roots. As an Irish surname form of Ó Raghallaigh (“descendant of Raghallach”), it carries a sense often glossed as “valiant” or “courageous,” reflecting the reputation of the medieval O’Reilly clan of Bréifne (centered in present-day County Cavan). In parallel, it aligns with the English place‑name Riley, from Old English ryge “rye” + leah “wood/clearing,” yielding the bucolic meaning “rye clearing.” These twin etymologies make Reiley a name that can signify both bravery and pastoral landscape.
As a given name, Reiley is a modern respelling that gained traction in the late 20th and early 21st centuries alongside the popularity of Riley/Reilly. It is used for all genders, with broader contemporary use in the United States and other English‑speaking countries. Related variants include Riley, Reilly, Reily, Reilley, Ryley, Rylie, Rylee, and Rileigh; O’Reilly remains the customary Irish surname form.
