PROBLEM TO BE SOLVED: To provide an alcohol-containing fuel injection control device for executing accurate air-fuel ratio control corresponding to various types of fuel to be used, different in alcohol content, without increasing cost for a control system. SOLUTION: An electronic control unit 14 as the alcohol-containing fuel injection control device is arranged in the fuel injection control system for an engine 1 for adjusting the injection of alcohol-containing fuel into a feedback system while detecting an output signal from an O2 sensor 8 as an air-fuel ratio sensor to execute air-fuel ratio control. The unit detects a changeover signal outputted from a changeover switch 15 as a changeover means for the changeover operation of a control content. Then, the unit selects the control content adequate to the alcohol-containing fuel to be used out of the plurality of types of control contents corresponding to alcohol contents previously stored in a storage means to execute the control.
