Browse nicknames →The Story of Sullivan
Sullivan derives from the Irish surname Ó Súilleabháin, meaning 'descendant of Súilleabhán,' where 'súil' means 'eye' and 'dubhán' or 'dubh' means 'dark' or 'black,' giving the overall sense of 'dark-eyed' or possibly 'hawk-eyed.' The O'Sullivan clan was one of the most powerful Gaelic dynasties in Munster (southern Ireland), making this one of the most common Irish surnames and a name with centuries of Celtic heritage.
Sullivan has risen dramatically as a first name in the US since the 2000s, following the trend of Irish surnames repurposed as given names. The nickname Sully gives it an approachable, friendly quality while the full name carries gravitas. It broke into the US top 500 boys' names around 2010.
The O'Sullivan clan's history spans the Norman invasions, the Elizabethan wars in Ireland, and the Irish diaspora following the Great Famine. As a given name, Sullivan carries this rich Irish heritage while sounding thoroughly at home in modern English-speaking cultures.
