Boo-Boo Bear is a Hanna-Barbera cartoon character on The Yogi Bear Show. He is an anthropomorphic cub in a bow tie, who acts as a sidekick to Yogi Bear. In the 2010 CGI/live-action Yogi Bear film he is voiced by Justin Timberlake.
Both he and Yogi appear in a flashback in the episode "Hell Comes to Quahog", where he witnesses Peter Griffin kill Yogi. Peter then tells Boo-Boo to tell all the other bears about what he has seen.
