Meaning & Origin
A surname.
Sloan is a girl's and boy's baby name of Irish origin, from the Irish surname Ó Sluagháin — derived from sluagh meaning 'army,' 'host,' or 'warrior.' As a given name, Sloan has become popular in the U.S. since the early 2000s, particularly for girls.
Sloan has a cool, modern confidence — one syllable, no frills, instantly strong. The TV series Entourage's character Sloan and Grey's Anatomy's Mark Sloan (whose last name became iconic) kept it in pop culture circulation. It sits beautifully alongside Quinn, Reese, and Drew as a sleek, gender-flexible surname name with genuine Irish heritage.
