A thumb ring is a ring meant to be worn on one's thumb. Most commonly, thumb rings are used as an archery equipment designed to protect the thumb pulp from the bowstring during a thumb draw, and are made of leather, stone, horn, wood, bone, antler, ivory, metal, ceramics, plastic or glass. It usually fits over the distal phalanx of the thumb, coming to rest at the distal edge of the interphalangeal joint. Typically a flange extends from the ring to cover the thumb pulp, and may be supplemented by a leather extension.

In some cultures, thumb rings also serve a decorative function like other types of rings, and are used to signal social status or ranks. In East Asia, such thumb rings are usually made of jade.
