Sloane comes from the Irish surname Ó Sluaghadháin, from the Old Irish sluaghadh, meaning "raid" or "hosting" (a military expedition). The name carries the meaning "warrior" or "raider."
Sloane has risen dramatically as a girl's first name since the 2010s. Today it sits in the U.S. top 200. The character Sloane Peterson in Ferris Bueller's Day Off (1986) is a famous early bearer.
Sloane does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Sloane reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
