A piston for an internal combustion engine may include a piston body including a piston skirt, a piston head, and a pocket. The piston head may include a cooling channel for receiving a cooling medium. The cooling channel may be open on a side facing away from a piston crown. The piston may also include at least one cooling channel cover at least partially closing the cooling channel, and a piston pin boss having a boss bore configured to accommodate a piston pin. The piston may further include a piston pin lubricating channel fluidically connected to the cooling channel and extending in a direction of the piston pin. The pocket may at least partially define the piston pin lubricating channel. The at least one cooling channel cover may have at least one lug that is offset radially inward and may, together with the pocket, define the piston pin lubricating channel.
