The stair-climbing hand truck is an improved hand truck that includes a back plate with a plurality of secondary wheels that may be used to roll the hand truck along a floor surface or up or down a flight of stairs. The back plate is rigidly affixed to the vertical frame of the hand truck. Moreover, the back plate is acutely oriented behind the vertical frame. The back plate has at least one wheel on opposing sides, which adaptively interact with a ground surface to roll the entire assembly. The vertical frame and the back plate are supported with primary wheels that are located adjacent to where the vertical frame meets a load plate. The primary wheels have a diameter larger than the wheels of the back plate.
