Abstract: An illuminated holder for storing one roll of toilet paper in a protected and conveniently accessible position atop a toilet tank, although positioning in other conveniently accessible locations in a bathroom is also contemplated. The holder has a grooved base, a cylindrical main body, an upwardly-tapering cap, and a light emitting diode (LED) that provides a source of illumination through a translucent light shield positioned between the main body and the cap. A photovoltaic cell and rechargeable battery preferably power the LED light, and a sensor automatically activates the LED light in dimly lit surroundings. One roll of toilet paper is placed on the base at a time, and then covered until needed by the assembled main body, shield, and cap. Optionally, the base may have high-friction feet configured for gripping the top of a toilet tank cover and maintaining the holder in its desired position of use.
