Relatively tall jacks which include a small base plate and an elongated vertical post are unstable under many operating conditions due to the height of the stem and the relatively small base provided. The present device is a stand adapted to receive such jacks and to provide a relatively safe support thereto. The jack stand includes a rectangular base with stabilizing pans extending outwardly therefrom and a pair of wheels which engage the ground when the jack stand is tipped so that it can be maneuvered into position. A pair of vertical supports extend upwardly from the stand surmounted by an apertured brace through which the jack stand extends and is retained. The base of the jack is detachably secured to the base of the stand. A handle is provided at the upper ends of the support for maneuvering the jack and stand upon the two wheels and a bale detachably supports the actuating handle of the jack against the stem when not in use.
