Avataro Sentai Donbrothers (暴太郎戦隊ドンブラザーズ, Abatarō Sentai Donburazāzu, Avataro Squadron Donbrothers) is a Japanese tokusatsu television drama, the 46th entry in Toei's long-running Super Sentai series and the third produced in the Reiwa era. The series is a semi-sequel to the previous entry, Kikai Sentai Zenkaiger, and premiered one week after its ending, joining Kamen Rider Revice and later, Kamen Rider Geats in the Super Hero Time lineup on TV Asahi on March 6, 2022. The series is loosely based on the Japanese folktale of Momotarō and the heroes fight monsters whose designs pay tribute to previous installments of the franchise.

Donbrothers began airing in South Korea as Power Rangers Don-Brothers. It was also the first series of the franchise since Gaoranger to air officially in mainland China.
