A start control device for a hybrid vehicle includes a battery, first and second rotary electric machines, an engine, a first determination unit configured to determine whether the battery is in a low output state, a cranking control unit configured to perform a cracking of the engine, and a second determination unit configured to perform a cranking completion determination. In a case where a maximum output of the battery is in the low output state, the cranking control unit causes the first rotary electric machine to run at a low output target rotation speed, and the second determination unit determines that the cranking is completed when a condition that an actual rotation speed of the first rotary electric machine continues to be within a target range for a predetermined time is satisfied.
