Abstract: A disposable cup dispenser designed to be mounted on an existing wall-mounted cup holder. The cup dispenser is comprised of a hollow tube and gasket ring wherein the gasket ring is attached to the bottom of the hollow tube and serves as the means of mounting the dispenser to the cup hole of the wall-mounted cup holder. The hollow tube or the gasket ring contains means for ensuring that only one cup is dispensed at a time. Cups are then dispensed downwardly out of the hollow tube and through the gasket ring and cup holder. The dispenser may also have a hinged or removable top.
