Reilley

Reilley is a masculine name representing a variant spelling of the traditional Irish surname Riley (Ó Raghailligh), meaning 'valiant' or 'courageous.' This particular spelling adds a distinctive touch to the increasingly popular practice of using Irish surnames as given names. While maintaining the friendly, approachable quality of Riley, the 'ei' combination and double 'l' give Reilley a more traditional Irish appearance. The name projects a spirited, energetic character with strong Celtic associations. Though less common than Riley, this spelling variation has gained some traction among parents seeking to honor Irish heritage while providing a slightly more distinctive name. Reilley works well across age groups, from childhood through adulthood, and carries positive connotations of bravery and liveliness.

Pronounced RY-lee.
