Riley

Riley comes from the Irish surname O'Reilly, likely derived from the Old Irish name Raghallach, composed of elements meaning "courage" and "valor." As a given name it became popular in the 20th century, and its firmly gender-neutral status has made it one of the most versatile names in contemporary use — equally at home on any companion.

Riley holds #36 among US pet names, with nearly 2,000 companions sharing it. The name has a breezy, confident quality that feels modern without trying too hard. Riley suits companions who are sociable and energetic, always up for whatever comes next, fully present in each moment. Its gender neutrality is part of its appeal — owners who want something contemporary and unfussy without committing to traditional masculine or feminine names find Riley an easy and satisfying choice.
