An exhaust gas purification system for a hybrid vehicle is disclosed. An internal combustion engine and an electric motor are each arranged for providing power output for the vehicle. An exhaust gas purification device is provided in an exhaust gas passage of the engine to treat exhaust gas components contained in the exhaust gas from the engine. A controller is arranged and configured to selectively perform a regeneration operation of the exhaust gas purification device to burn and remove deposits accumulated in the exhaust gas purification device. The controller is further arranged and configured to control the internal combustion engine and the electric motor such that the exhaust gas purification device is restrained from reaching an excessive temperature during the regeneration operation of the exhaust gas purification device.
