To provide a start control device 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 the EV reverse starting. A first motor/generator (MG1), an internal combustion engine (ICE), and a multistage gear transmission (1) are provided. In this hybrid vehicle, the multistage gear transmission (1) is provided with a third electric actuator (33) that selects an EV gear shift stage, and a first electric actuator (31) and a second electric actuator (32) that select an ICE gear shift stage. A transmission control unit (23) is provided, which causes the third electric actuator (33) to select EV 1st of the multistage gear transmission (1) at the time of starting, and that carries out an EV starting using the first motor/generator (MG1) as the drive source. The transmission control unit (23) is configured as a mechanism that prevents the selection of the ICE gear shift stage by the first electric actuator (31) and the second electric actuator (32) at the time of an EV reverse starting, and rotates the first motor/generator (MG1) in a direction opposite to the forward direction of rotation of the internal combustion engine (ICE).
