Killer Bob (or simply Bob) is a fictional character in the ABC television series Twin Peaks. He is a demonic entity who feeds on fear and pleasure. He possesses human beings and then commits acts of rape and murder in order to feast upon his victims.

Bob made his first appearance in the pilot episode, "Northwest Passage", where he makes a brief cameo in a vision had by Sarah Palmer. The character eventually grew into the series' primary antagonist in the second season. Frank Silva, a set dresser on the pilot, was given the role of Bob after a reflection of his face in a mirror was accidentally captured by the camera during filming. When series creator David Lynch saw Silva's face, he liked it so much he kept it in the show, and cast Silva as Bob.

In 2016, Rolling Stone ranked him #5 of their "40 Greatest TV Villains of All Time".

Bob is a demonic entity from the Black Lodge, a realm of pure evil which exists on an alternate plane of reality. While possessing humans, he commits horrible crimes to elicit pain, fear, and suffering from those around him.

Dale Cooper first learns of Bob's existence in a vision, in which he encounters another entity named Mike. In this vision, Cooper learns that Bob was in life a serial killer who raped and murdered young women, with Mike as his accomplice. Mike eventually repented, removing his left arm in order to be rid of the tattoo that he shared with Bob. At the beginning of the second season, one of Bob's intended victims, Ronnette Pulaski, awakens from a coma induced by her torture at Bob's hands, at which time she identifies Bob as Laura's killer. Cooper and the Twin Peaks Sheriff department canvass the town with wanted posters of Bob, using Andy's sketch. Leland Palmer, Laura's father, identifies the man in the poster as "Robertson", and says that he lived near his grandfather and used to taunt Leland when he was a child.
