Abstract: A beverage holder attachment for a crutch has an annular cup holder portion and two molded C-shaped protrusions for snapping onto two side rails of a crutch. The cup holder has a vertical slot on the outside to accommodate a handle of a mug or cup. The cup holder sits in between the two rails of the crutch below the hand bar so that it does not interfere with the use of the hand bar. The cup holder is tilted slightly to avoid spillage on the user of the crutches, so that any coffee drips will spill on the outside of the crutch. The beverage holder can be snapped onto the crutch side rails to carry beverages or other objects around the home or office while on crutches. The beverage holder can be made out of plastic, rubber or any other molded material that will snap onto the crutch.
