Meaning & origin

Reily is a modern, unisex name that emerged in the early 1990s, first recorded in 1992. It saw a peak in popularity in 2006, but has been falling since 2007, reflecting a broader trend away from similar-sounding names. While not currently in the top 1000, Reily remains a choice for parents seeking a familiar yet distinctive variant of Riley. Its spelling sets it apart, but the name has not been strongly associated with any particular US state or demographic. The name's dual Irish and English heritage gives it a versatile appeal, and its simplicity ensures it is easy to pronounce and spell. As a variant of a well-established name, Reily carries the same positive associations of charm and approachability.

Reily is a modern spelling variant of Riley, which itself has multiple possible origins. It may derive from the Irish surname O'Reilly or from an English place name meaning 'rye clearing'. As a given name, it emerged in the late 20th century, influenced by the popularity of similar-sounding names like Riley and Rylee.
