A wedding ring or wedding band is a finger ring that indicates that its wearer is married. It is usually forged from metal, traditionally gold or another precious metal. Rings were used in ancient Rome during marriage, though the modern practice of exchanging rings during weddings has a Christian origin.

Depending on the culture, a wedding ring is typically worn on the base of the left ring finger; if the wearer is left-handed, often it will go onto the right hand. The ring finger is widely claimed to be associated with the traditional belief known as vena amoris ("vein of love"). Many spouses wear their wedding rings day and night, causing an indentation in the skin that is visible even when the ring is removed.
