Bakugan Battle Brawlers (爆丸 バトルブローラーズ, Bakugan Batoru Burōrāzu) is a Japanese anime television series produced by Nelvana Animation and TMS Entertainment under the direction of Mitsuo Hashimoto. The story centers on the lives of creatures called Bakugan and the "battle brawlers" who possess them. The Bakugan franchise itself is a joint venture between Sega Toys, Spin Master and Nelvana.

Although originally broadcast by TV Tokyo in Japan, follow-up seasons (New Vestroia and Gundalian Invaders) premiered in Canada and the US before Japan. The fourth and final season, Mechtanium Surge, was never broadcast in Japan and instead aired in North American markets. However, a Japan-exclusive manga series, Baku Tech! Bakugan, ran from August 15, 2010, to January 15, 2014. This received an anime adaptation aired on TV Tokyo from April 7, 2012, to March 30, 2013, followed by a second season called Baku Tech! Bakugan Gachi which ran from April 6, 2013, to December 28, 2013.

In 2015, Spin Master and Nelvana revealed plans to relaunch Bakugan. The relaunch was later announced on November 30, 2017, to occur in the first quarter of 2019, with the series title announced as Bakugan: Battle Planet. The new series premiered on Cartoon Network in the United States on December 23, 2018, while Canada's Teletoon premiered the series on December 31, 2018.

On June 16, 2023, a trailer for another reboot of Bakugan was released on YouTube. The reboot was released on Netflix on September 1, 2023 and started airing on Disney XD on September 23, 2023. The first two episodes were previewed on Roblox on August 4, 2023.
