Providing a vehicle engine start control device capable of suppressing a feeling of discomfort brought to a driver and rapidly and certainly starting an engine when the automatically stopped engine is restarted. The engine 12 is stopped with the crank angle AG CR controlled such that the crank angle AG CR at the time of automatic stop of the engine falls within the crank angle stop range AG ST . The engine rotation resistance control means 132 provides the engine rotation resistance control in which the engine rotation resistance generated due to a change in air pressure in the combustion chamber of the engine 12 is made larger while the engine 12 is in the automatic stop period, as compared to the time of engine start. Therefore, since the crankshaft 14 is hardly rotated by an external force while the engine 12 is in the automatic stop period and the crankshaft 14 is stopped within or in the vicinity of the crank angle stop range AG ST that is favorable engine startability at the time of restart of the engine 12, the engine can quickly and certainly be started while suppressing a feeling of discomfort brought to a driver.
