Provided is a piston temperature state monitoring system for an internal combustion engine and a piston temperature monitoring method for an internal combustion engine which are capable of properly managing a history of a piston temperature. When the number of times of a piston temperature suppression control is counted, if a ratio of a temperature difference which is the difference between a maximum limit temperature and a piston temperature to a margin width which is the difference between the maximum limit temperature and a control start temperature is equal to or less than a count threshold ratio set in advance or calculated, a count output system outputs a count signal.
