PROBLEM TO BE SOLVED: To provide a water-based coating composition for a can, having excellent finishability because of good wettability on a wet ink, having water resistance resisting to retort treatment, being hardly scratched in a transportation process of the can because of a high-hardness coated film, and providing a coated film having excellent slipperiness at processing. SOLUTION: The water-based coating composition for the can contains (A) a carboxy group-containing vinyl copolymer resin, (B) a crosslinking agent comprising at least one kind selected from a melamine resin and a benzoguanamine resin, and an oxazoline group-containing compound, (C) a silicone-based additive and (D) a wax, wherein the contents of the specific silicone-based additive (C) and the wax (D) are 0.1-10 pts.mass and 0.01-10 pts.mass respectively based on 100 pts.mass of the total of the solid components of the carboxy group-containing vinyl copolymer resin (A) and the crosslinking agent (B).
