A self-service laundry, coin laundry, laundromat or coin wash is a facility where clothes are washed and dried without much personalized professional help.

Laundromats 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). In Texas and other parts of the south central United States, the term washateria is still used by some older speakers. It is known that George Edward Pendray was the one to create the term "laundromat" for Westinghouse.
