"Know the Ledge" – originally on the soundtrack of the film Juice as "Juice (Know the Ledge)" – is a 1992 single by hip-hop duo Eric B. & Rakim. The film's theme song, also released on the duo's 1992 album Don't Sweat the Technique, it features a distinctive sample from Nat Adderley's 1968 hit "Rise, Sally, Rise".

"Know the Ledge" showcases Rakim's storytelling ability, sharing a first-person narrative of a neighborhood thug and drug dealer forced to come to grips with his violent and reckless lifestyle. Among Eric B. & Rakim's final hits as a duo, it was one of the most successful singles from the Juice soundtrack.

50 Cent told NME that the song was the one that made him want to be a rapper: "They were painting a picture of where I lived and all the moves you needed to make in order to live on the streets there. It was the law of the jungle out there."
