Disclosed is a cooling duct (6) for a piston (1) of a combustion engine. The cooling duct (6) has an annular shape and comprises two openings (7, 8) which are arranged next to each other and are alternately used as inlets as well as at least one outlet (15, 16) on the side of the cooling duct (6) located radially opposite the openings (7, 8). In order to allow the oil to more easily flow through the cooling duct (6) and thus the piston (1) to be better cooled, the cooling duct (6) has two outlets (15, 16) that are arranged next to each other as well as a reduced cross-section (17) which lies between the two outlets and acts as a throttle.
