PROBLEM TO BE SOLVED: To provide a fuel injection control device for a cylinder injection spark ignition type internal combustion engine capable of effectively preventing adhesion of fuel to a cylinder wall surface and improving exhaust gas characteristics. SOLUTION: In this fuel injection control device for the cylinder injection spark ignition type internal combustion engine, the fuel injection control device is provided with a total required fuel amount calculating means (S16) to calculate a total required fuel amount according to the operation condition of the internal combustion engine, and a first limit injection control means (S20) in which a first limit fuel amount is calculated (S200) in which fuel spray may not reach a cylinder wall by one fuel injection at the time of a first fuel injection during intake stroke, and while, when the total required fuel amount is larger than the first limit fuel amount, fuel is ejected by the first limit fuel amount at the time of the first fuel injection (S206) and also the rest of a first remaining fuel amount (S208) is ejected before the end of compression stroke after the end of the first fuel injection, the total required fuel amount is ejected all at once at the time of the first fuel injection (S204) when the total required fuel amount is below the first limit fuel amount.
