PROBLEM TO BE SOLVED: To provide a warming-up apparatus of an internal combustion engine for appropriately avoiding a decrease in the recovery efficiency of a heating medium. SOLUTION: The warming-up apparatus of the internal combustion engine is applied to a hybrid vehicle for mounting a navigation system NS, thus supplying cooling water stored in a heat-storing tank 21 to the internal combustion engine 11 via an electric water pump 22, and hence promoting the warming-up of the internal combustion engine 11. When the current location of the hybrid vehicle in the navigation system NS arrives around a destination set to the navigation system NS, the cooling water that absorbs heat in the internal combustion engine 11 and becomes a high temperature is recovered into a heat-storing tank 21 through the electric water pump 22.
