Meaning & origin

Sullivan, an Irish surname turned given name, has been rising steadily as a first name since the mid-1980s. It first appeared on U.S. birth records in 1884, but its real ascent began around 1986. In 2025, it ranked 314th, with a 1-in-1,577 frequency, and reached its highest popularity ever that same year. The name is strongest in Vermont, Maine, and Minnesota, reflecting its appeal in states with strong Irish heritage. Sullivan's blend of surname prestige and soft Irish charm makes it a distinctive yet accessible choice.

Sullivan is an Anglicized form of the Irish surname Ó Súilleabháin, meaning 'descendant of Súilleabhán'. The personal name Súilleabhán is derived from súil (eye) and the diminutive suffix -án, often interpreted as 'dark-eyed' or 'hawk-eyed'. The Ó Súilleabháin clan was historically prominent in County Kerry and County Tipperary. As a given name, Sullivan gained popularity in the late 20th century, following the trend of using surnames as first names.
