A hybrid vehicle start control device is provided for a hybrid vehicle that ensures an EV reverse starting intended by a driver, even when an engagement command is issued to an engagement clutch that selects an ICE gear shift stage, when carrying out EV reverse starting. In this hybrid vehicle, a multistage gear transmission includes an EV shift actuator that selects an EV gear shift stage, and ICE shift actuators that select an ICE gear shift stage. A starting controller operates the EV electric actuator to select EV 1st of the multistage gear transmission at a time of starting, and that carries out an EV starting using the first motor/generator. At a time of an EV reverse starting, the starting controller carries out a control to the operating positions of the ICE shift actuators that prevent the selection of the ICE gear shift stage by the ICE shift actuators.
