A startup control apparatus of an internal combustion engine including a supercharger having a turbine driven by exhaust gas from the internal combustion engine, a variable nozzle mechanism provided in the supercharger and regulating the flow rate of exhaust gas to the turbine, and an exhaust gas control catalyst arranged in an exhaust passage on the downstream side, with respect to the direction of exhaust gas flow, of the turbine. A controller selectively performs, during a cold start, control to increase the amount of combustion gas in a cylinder of the internal combustion engine by reducing the sectional area of a nozzle passage of the variable nozzle mechanism and increasing back pressure, and controls to deliver exhaust gas to the exhaust gas control catalyst by increasing the sectional area of the nozzle passage of the variable nozzle mechanism.
