PROBLEM TO BE SOLVED: To provide a fuel injection control device of a direct injection internal combustion engine, capable of performing effective divided injection, by surely securing its function on respective injections of the divided injection. SOLUTION: A control part 30 of the internal combustion engine divides a fuel injection quantity set on the basis of an engine operation state into an intake stroke and a compression stroke on the basis of the predetermined injection quantity ratio. The control part 30 sets a lower limit value on a compression stroke injection quantity among these intake stroke injection quantity and compression stroke injection quantity; equally sets the compression stroke injection quantity and the lower limit value when the compression stroke injection quantity is less than its lower limit value; and reduces a difference of these (a difference between the compression stroke injection quantity and the lower limit value) from the intake stroke injection quantity.
