The controller is configured to execute catalyst warm-up control for warming up a catalyst of the exhaust emission control device. The catalyst warm-up control includes first control and second control. The first control is control for operating the internal combustion engine at a first operating point. The second control is control for, after the first control is executed, operating the internal combustion engine at a second operating point irrespective of a driving force that is required to propel the hybrid vehicle. An output of the internal combustion engine at the second operating point is larger than an output of the internal combustion engine at the first operating point. The controller is configured to operate the internal combustion engine while an ignition timing of the internal combustion engine at the time when the first control is executed is set to a retarded side with respect to an ignition timing of the internal combustion engine at the time when the second control is executed. The controller is configured to, when the first control is executed, control the variable valve actuating device such that the operation characteristic becomes the first characteristic. The controller is configured to, when the second control is executed, control the variable valve actuating device such that the operation characteristic is changed to the second characteristic. The controller is configured to, after the second control is executed, operate the internal combustion engine on the basis of the driving force that is required to propel the hybrid vehicle and control the variable valve actuating device on the basis of a rotation speed and torque of the internal combustion engine.
