A piston for an internal combustion engine has a piston crown, a circumferential fire land, a circumferential ring part having annular grooves, and a piston skirt, which comprises two skirt walls and two box walls set back from the ring part and connecting the skirt walls in such a way that an exposed underside of the ring part is formed in the area of each of the box walls. The box walls are provided with pin bosses having pin bores. At least one support element is arranged between each exposed underside of the ring part and the box wall associated with the underside of the ring part.
