Provided is a control device for an internal combustion engine, which is configured to: acquire an internal combustion engine required opening degree of the waste gate valve based on the operation state of the internal combustion engine. When the internal combustion engine required opening degree is full closing, full closing learning control is carried out by converting the target opening degree of the waste gate valve to a target opening degree for full closing learning so as to bring about a state in which the waste gate valve fully closes the exhaust bypass passage. When a state in which the position of the actuator does not change consequently continues for a set period, it is considered that the fully closed state is brought about and the full closing learning is finished, and a correction amount for the feedback control is decreased.
