A knocking control system for an internal combustion engine comprising knocking detector for detector an occurrence of a knocking, first control element for controlling a combustion in an engine combustion chamber based on signals from the knocking detector, first knocking suppressing device for determining a first control gain to control the first control element and thereby suppressing a knocking, second control element for controlling the combustion in the combustion chamber, second knocking suppressing element for determining a second control gain and for controlling the second control element when the first control gain for the first control element is more than a predetermined value, and gain changing element for changing the first control gain to a smaller value as the second control gain is increased. The control system performs quicker knocking control by the first and second control element.
