Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fuel injection control apparatus for internal combustion engine which can accurately estimate a catalyst bed temperature even when a wall flow rate of a fuel injection port fluctuates.SOLUTION: The fuel injection control apparatus for internal combustion engine, which controls an amount of fuel injection to the fuel injection port 111a of an intake passage 111, includes a catalyst bed temperature estimation means 11 for estimating a catalyst bed temperature of a catalyst 127 which is provided in an exhaust passage 125, a control means 11 for controlling an amount of fuel injection on the basis of the catalyst bed temperature, and a wall flow rate estimation means 11 for estimating a wall flow rate of the fuel injection port. The catalyst bed temperature estimation means corrects the catalyst bed temperature depending on the wall flow rate.
