Danny is the familiar form of Daniel, the Hebrew name that means "God is my judge", after the prophet who survived the lions' den. Given on its own, it has a warm, boy-next-door feel known from Danny Zuko in Grease and the actor Danny DeVito. Danny ranked number 286 in the United States in 2000, peaked at number 269 in 2002 and has drifted to number 628 in 2025 as parents prefer the full Daniel.
