Edward 'Ed' Grimley was a character introduced on the television series SCTV and later used in Saturday Night Live. He was devised and played by actor Martin Short.

He is a nerd with a large frontal cowlick who obsessed with banal popular culture, especially Wheel of Fortune and its host, Pat Sajak. He also loves to play the triangle, which for him consists of playing a recorded musical piece, striking the triangle once, and then wildly dancing to the recording.

After achieving popularity on SNL, Grimley became a cartoon character on Hanna-Barbera's animated show The Completely Mental Misadventures of Ed Grimley (1988). In each episode, Grimley would have an adventure of some sort, interspersed with science lessons from The Amazing Gustav Brothers, and a 'scary story' presented as a show-within-a-show by Grimley's favourite television host: Count Floyd.
