A control apparatus for an internal combustion engine includes: a fuel property sensor which is provided between a fuel tank and a delivery pipe and which detects a component ratio of fuel; a fuel property value calculator that calculates an injector fuel property value for each cylinder using the component ratio detected by the fuel property sensor a period of time ago, which is equal to an amount of time required for the fuel to travel from the fuel property sensor to each fuel injector, as a value corresponding to the present component ratio of the fuel near the corresponding injector; and an engine-restart-time fuel injection amount calculator that calculates a fuel injection amount for each cylinder based on an engine-off duration in a case where the internal combustion engine is restarted after the internal combustion engine is stopped when the injector fuel property value varies from cylinder to cylinder.
