A control device controls an internal combustion engine including a piston jet that injects lubricating oil to a back surface of a piston and an oil pump that changes a unit discharge amount that is a discharge amount of the lubricating oil per revolution. The control device includes a processing circuit. The processing circuit is configured to close an electric valve provided on a supply path of the lubricating oil to the piston jet to stop injection of the lubricating oil from the piston jet when an oil temperature is lower than a predetermined temperature. The processing circuit is configured to maintain the unit discharge amount of the lubricating oil discharged from the oil pump at a predetermined amount or more while the injection of the lubricating oil from the piston jet is stopped when the oil temperature is lower than the predetermined temperature.
