The clothing iron holder with water reservoir is a protective accessory for use with a clothing iron or the like. The holder includes a water reservoir having a front portion, a central portion, and a rear portion, and is sized and shaped to receive the clothing iron. The front portion has an opening formed therethrough for releasably covering and connecting to a water fill opening of the clothing iron such that water exiting the water fill opening is received within the water reservoir. Thus, if the iron accidentally falls or is tipped over, the water will spill into, and be collected within, the water reservoir.
