Sloane is an Irish surname, from Ó Sluaghadháin, that goes back to the word sluaghadh and means "raider" or "warrior". The name is linked to Sloane Square in London and to Sloane Peterson in the 1986 film Ferris Bueller's Day Off, which introduced many Americans to it as a girls' name. Sloane entered the US top 1000 in 2009, climbed from number 327 in 2015 to a peak of number 140 in 2022 and ranks 141st in 2025.
