Tekkaman Blade (Japanese: 宇宙の騎士テッカマンブレード, Hepburn: Uchū no Kishi Tekkaman Burēdo) is a 1992 Japanese anime television series produced by Tatsunoko Production and Sotsu Agency. The series was directed by Hiroshi Negishi and written by Mayori Sekijima and Satoru Akahori. The story follows an organization called the Space Knights and their war against aliens known as the Radam. The Space Knights are assisted by Takaya Aiba, who has the ability to transform into an armored warrior known as Tekkaman Blade.

The first series, of 50 episodes (including episode 0), aired in Japan from February 18, 1992, to February 2, 1993, on TV Tokyo. This was followed by two specials. A sequel series called Tekkaman Blade II, which is set ten years after the first series and follows the events of the second Radam invasion, was a series of six Japanese original video animation (OVA) releases from July 21, 1994, to April 21, 1995.

The original series was released internationally, including North America, and was dubbed in English as Teknoman. In the English-dubbed versions, the series was heavily cut compared to the original Japanese version and shortened from 50 to 43 episodes.
