Rebecca Rea Sugar (born July 9, 1987) is an American animator and screenwriter. She is best known for being the creator of the Cartoon Network series Steven Universe, making her the first non-binary person to independently create a series for the network. Until 2013, Sugar was a writer and storyboard artist on the animated television series Adventure Time. Her work on the two series has earned her seven Primetime Emmy Award nominations.
