Clumsy Smurf is one of the Smurfs in the Smurfs. He is Brainy's best friend.
- In the 80's cartoon series, he was voiced by Bill Callaway and had a Southern accent. In the live-action film series and Sony animated shorts, he is voiced by the late Anton Yelchin and his Southern accent was dropped. He is voiced by Jack McBrayer (Fix-It Felix from Wreck-It Ralph) in the fully animated Smurfs: The Lost Village, and regained his Southern accent from the 80's cartoon series.
