Abstract: An illuminating beverage container cooler. The sleeve of the cooler is made of a flexible thermally insulating material, such as neoprene, and the base of the cooler is made of a rigid material with lights and necessary batteries installed within a containment compartment in said base. The lights, when turned on, result in the portion of the bottle above the insulating cylindrical sleeve sidewalls being illuminated. The illuminating cooler also functions as a flashlight when the beverage container is removed.
