A catalyst warm-up control method for a hybrid vehicle includes a battery supplying electric power to an electric motor, the battery is charged by an engine for electric power generation, and exhaust gas discharged from the engine 1 is treated by a catalyst. By the catalyst warm-up control method, when temperature of the catalyst is lower than required warm-up temperature for activating the catalyst, target revolution speed and target torque of the engine are controlled based on a state of charge of the battery, and, when target revolution speed is lower than lower-limit revolution speed at which the catalyst can be heated to the required warm-up temperature, the target revolution speed is controlled so as to be required warm-up revolution speed that is equal to or higher than the lower-limit revolution speed.
