History & Origin

Riley derives from the Irish surname Ó Raghallaigh, anglicized as O'Reilly or Riley, meaning 'descendant of Raghallach.' The personal name Raghallach is thought to derive from Gaelic elements meaning courageous or valiant. Like many Irish surnames, Riley crossed to America with 19th-century immigration waves and began converting to a given name in the 20th century.

Riley was initially used as a boys' given name but crossed to girls in significant numbers during the 1990s. By the 2000s it was climbing the girls' charts rapidly, entering the top 25 by the mid-2010s. It is now one of the most familiar crossover names in the U.S., though it retains modest male use as well.

Did you know? Riley became widely known as a girls' name partly through the lead character Riley Matthews in the Disney Channel series Girl Meets World (2014–2017).
