Astro Fighter Sunred (天体戦士サンレッド, Tentai Senshi Sanreddo) is a Japanese manga created by Makoto Kubota.

The story revolves around the Tama River area, based mostly in Kawasaki City Kanagawa where battles are fought between the evil organisation Florsheim and the ally of justice Sunred.

The twist is that Sunred (referred to most characters familiar with him as simply 'Red') is a rough-talking, violent and rude hero while the villains of Florsheim (led by General Vamp) are for the most part polite, conscientious and easy-going.

Most of the humour comes from the interactions of the characters, especially the main trio of Sunred, his girlfriend Kayoko and General Vamp.

Twenty volumes have been published by Flex Comix in Japan, and by Tong Li Comics in Taiwan.
