A warm-up control device for a vehicle includes a battery supplying electricity to a motor that drives a vehicle and can be charged with a current supplied from the exterior of the vehicle, and a heater generating heat that warms up the vehicle by the above current. The warm-up control device further includes a temperature acquisition unit acquiring a temperature of the battery, and a current distribution control unit increasing a heater supply current supplied to the heater as the temperature of the battery decreases. This can effectively utilize energy from an external power source for the charging and warming-up, thus improving the energy saving performance.
