PROBLEM TO BE SOLVED: To provide a fuel injection control device of a multicylinder engine capable of realizing performance suitable for actual travel, by restraining deterioration in engine performance caused by specifications of a cylinder in the whole operation area. SOLUTION: This engine (1) has a low speed specification cylinder by three cylinders and a high speed specification cylinder by three cylinders, and controls respective fuel injection valves (2) so as to respectively inject a fuel injection quantity q1+αincreased by a predetermined quantityαto the low speed specification cylinder and a fuel injection quantity q1-αreduced by the predetermined quantityαto the high speed specification cylinder in low speed operation, and controls the respective fuel injection valves so as to respectively inject a fuel injection quantity q2-βreduced by a predetermined quantityβto the low speed specification cylinder and a fuel injection quantity q2+βincreased by the predetermined quantityβto the high speed specification cylinder in high speed operation.
