The Tin Woodman (also known as the Tin Man or the Tin Woodsman) is a man who was turned into a being made entirely of tin and resides in the Land of Oz. He is one of Dorothy Gale's companions in L. Frank Baum's novel The Wizard of Oz.
After Dorothy left Oz and returned home to Kansas in Return to Oz, the Tin Woodman had been turned into a stone statue by the Nome King, but thankfully Dorothy defeats the Nome King and restores the Tin Woodman to his regular form. Among many other Ozians, he celebrates Dorothy's victory and witnesses the return of Oz's true ruler Ozma. He also says goodbye to Dorothy when she departs, but knows that she can return anytime if she wants.
In The Muppets' Wizard of Oz, Gonzo plays a character called the Tin Thing, an obvious spoof of the Tin Woodman. Like the story, the Tin Thing was turned into a robotic, computerized being without a heart by the Wicked Witch so that he could not love Camilla. Despite the handicap, the Tin Thing proves to be a useful companion to Dorothy Gale and the others, showing great friendship throughout.
