Digimon Fusion, known in Japan as Digimon Xros Wars (デジモンクロスウォーズ, Dejimon Kurosu Wōzu, pronounced "Cross Wars"), is the sixth anime television series in the Digimon franchise, produced by Toei Animation. The series was broadcast on TV Asahi and Asahi Broadcasting Corporation between July 2010 and March 2012.

Its storyline follows the adventures of Mikey Kudo, who utilizes the power to fuse any of his Digimon partners. The series is divided into three arcs, with the latter two given the subtitles of The Evil Death Generals and the Seven Kingdoms (悪のデスジェネラルと七つの王国, Aku no Desu Jeneraru to Nanatsu no Ōkoku), and The Boy Hunters Who Leapt Through Time (時を駆ける少年ハンターたち, Toki o Kakeru Shōnen Hantā-tachi) respectively.

The series was licensed outside of Asia by Saban Brands for an English-language adaptation, which was produced by Studiopolis; the third and final arc did not receive an English localization. The series was also adapted into a manga series and multiple video games.
