Invincible Steel Man Daitarn 3 (無敵鋼人ダイターン3, Muteki Kōjin Daitān 3), also known as The Unchallengeable Daitarn 3, is a Japanese anime television series created by Yoshiyuki Tomino and Hajime Yatate, and animated by Sunrise. It was first broadcast on Japanese TV in 1978. The series lasted for 40 episodes. The opening theme Come Here! Daitarn 3 is sung by Makoto Fujiwara. Despite being moderately successful in Japan, the series became very popular abroad, especially in Italy during the early 1980s.

Between 1989 and 1992, Tomino wrote several spin-off novels, which are collectively known as the Banjō Haran Series (破嵐万丈シリーズ, Haran Banjō Shirīzu, lit. "Full Vent to the Winds of Destruction Series").
