Band-Aid is a brand of adhesive bandages distributed by the consumer health company Kenvue, spun off from Johnson & Johnson in 2023. Invented in 1920, the brand has become a generic term for adhesive bandages in countries such as the United States, Canada, Australia, the Philippines, and others.

An adhesive bandage, also called a sticking plaster, medical plaster, or simply plaster in British English, is a small medical dressing used for injuries not serious enough to require a full-size bandage. They are also known by the genericized trademarks of Band-Aid or Elastoplast.
