自助洗衣店（英文：Self-service laundry）是提供自助洗衣及干衣等服务的商店。

传统的洗衣店，是由店家帮客户清洗衣服，但由于价格较高，因此大多是高单价的贵重衣物等才会交由洗衣店代为清洗。而在一些地方，如宿舍、旅馆等地的居住者有洗衣的需求，但因种种因素无法自己洗衣，因此自助洗衣店就应运而生。

大多数自助洗衣店采无人式经营，少部份会驻有人员。

A self-service laundry, coin laundry or coin wash is a facility where clothes are washed and dried. They are known in the United Kingdom as launderettes or laundrettes, and in the United States, Canada, Australia and New Zealand as laundromats (from the genericized trademark of the Westinghouse Electric Corporation) or washaterias. George Edward Pendray created the word "laundromat" for Westinghouse.
