A bracelet is an article of jewellery that is worn around the wrist. Bracelets may serve different uses, such as being worn as an ornament. When worn as ornaments, bracelets may have a supportive function to hold other items of decoration, such as charms. Medical and identity information are marked on some bracelets, such as allergy bracelets, hospital patient-identification tags, and bracelet tags for newborn babies. Bracelets may be worn to signify a certain phenomenon, such as breast cancer awareness, or for religious/cultural purposes.

If a bracelet is a single, inflexible loop, it is often called a bangle. When it is worn around the ankle it is called an ankle bracelet or anklet. A boot bracelet is used to decorate boots. Bracelets can be manufactured from metal, leather, cloth, plastic, bead or other materials, and jewelry bracelets sometimes contain jewels, rocks, wood, shells, crystals, metal, or plastic hoops, pearls and many more materials.
