"Believe It Or Not!" is a newspaper cartoon featuring unusual, hard-to-believe facts from around the world. The cartoon was conceived and drawn by Robert Ripley. It premiered on December 19, 1918 in the New York Globe.

"Believe It Or Not!" later became a radio program and then a television show.

Originally involving sports feats, Ripley first planned to call the cartoon "Chumps and Champs."
