A cock ring is a sex toy worn around the penis, usually at the base. The primary purpose of wearing a cock ring is to restrict the flow of blood from the erect penis to produce a stronger erection. It can also be used to increase girth and/or to maintain an erection for a longer period of time.

When used in cases of erectile dysfunction (ED), they are known by various other names, such as erection rings and tension rings. They are sometimes used as medical devices, on their own or in conjunction with a penis pump to assist in the management of erectile dysfunction.
