Princess Langwidere is a fictional character who is first introduced in L. Frank Baum's third Oz book titled Ozma of Oz, published in 1907. Langwidere is not the protagonist nor necessarily the antagonist in Baum's Oz novel. She is portrayed as an arrogant and pampered character of annoyance with a distasteful personality to entertain the reader for the plot of the story involving the return of Oz's main heroine and child protagonist named Dorothy Gale from Baum's first Oz book titled The Wonderful Wizard of Oz, published in 1900.
