The invention provides a stamping device (1) for stamping eggs (8). The stamping device comprises an egg conveyor with at least one conveyor track for eggs and a stamping element (6) disposed above the at least one conveyor track, on the bottom side of which stamping element a stamping surface (7) which is vertically movable relative to the path of movement of the eggs is provided, and which comprises ink supply means for supplying ink to the stamping surface. The stamping surface has a starting position spaced a first distance above the conveyor track on which the stamping surface is located in the path of movement of eggs to be stamped. The stamping surface can move upward relative to the starting position upon making contact with the shell of an egg passing under the stamping element in use of the device, such that the stamping surface will leave in imprint on the egg shell, with the stamping surface returning to the starting position after passage of the egg. The invention further provides a method for stamping eggs.
