Brave Exkaiser (勇者エクスカイザー, Yūsha Ekusukaizā, Sometimes translated as Brave Exkaizer or Brave Fighter Exkizer) is a Japanese animated television series produced by Sunrise. The series is directed by Katsuyoshi Yatabe and written by Yasushi Hirano with both character and mecha designs done by Masayuki Hiraoka and Kunio Okawara respectively. It aired on Nagoya TV from February 3, 1990 to January 26, 1991, consisting of 48 episodes.

Exkaiser is the first installment in Takara and Sunrise's Brave series franchise, spanning up to eight separate installments. It is generally one of the more influential anime in the 1990s, which revitalized the Super Robot genre in that time through both the series' reception as well as its toy sales. It would be later referenced and homaged in several other animated works.
