<P>PROBLEM TO BE SOLVED: To provide a fuel injection control device for a flexible fuel engine capable of suitably correcting wall surface adhesion of a fuel injection amount during transient operation even in the flexible fuel engine operated by injecting mixed fuel of alcohol and gasoline into an intake passage. Ž<P>SOLUTION: When correcting the wall surface adhesion of the fuel injection amount in the transient operation, an electronic control unit 22 distributes a total amount of the correction to an immediate correction term applied immediately in the change of the engine load and a tailing correction term attenuated according to the elapse of time after the change of the engine load. The mode of the correction is variable in accordance with the alcohol concentration so that the higher the alcohol concentration of the mixed fuel is, the more an absolute amount of the immediate correction term and an absolute amount of the tailing correction term are increased.
