太空飞鼠（英语：Mighty Mouse）是美国电影动画短片，剧集，卡通及漫画作品。以电影短片为首度亮相方式的该作品，首创于1942年，创造人为保罗特里工作室。在角色设置上，太空飞鼠主角是只拥有超能力的老鼠，并时常「扶弱锄强」。

创作初始，太空飞鼠穿着皆以知名漫画超人为模仿对象，如：蓝色服装，红色斗篷及「S」胸前英文标志，但随着剧集演进，渐渐发展成不同服装。例如蓝色服装变成了黄色服装，「S」胸前标志被取消，而只维持了原本设置的红色斗篷。

漫画时代的太空飞鼠，虽未大红大紫，但首创的漫画透视手法及超能力老鼠剧情，仍吸引一定阅读者目光。直至1955年，美国CBS公司买下太空飞鼠版权并随即推出太空飞鼠电视影集后，终于成为美国畅销卡通影集。1955年－1967年，该剧集占据了每星期六早上的儿童黄金时段，而该影集直到1980年代末期仍继续推出新剧情影集，取名为「新太空飞鼠」。
