日本学生泳衣（日语：スクール水着），是日本小学、初中、高中的游泳课程规定穿着之泳衣。

第二次世界大战后，发布了新的课程教育指引，规定小学、初中、高中要在体育课程加入游泳课。当时市面上贩卖的泳衣形状与活动性等并不适合用于游泳课程，因此依照比赛用之泳衣进行修改，设计出学校专用之泳衣。

Sukumizu(スク水), short for school mizugi(スクール水着,sukūru mizugi, lit. "school swimsuit"), is a variant of swimwear intended for use by school students during swimming lessons in Japan. They can come in the form of either a one-piece or a two-piece swimsuit for girls, the latter of which corresponds to a sleeveless shirt for the upper torso. Boys, on the other hand, generally wear swim trunks. They are usually coloured in a dark blue hue, are closely fitting, and have typical seam lines that run laterally across the chest for girls. The material is generally a mixture of synthetic fibers such as nylon and polyester.
