A knocking control system for a gas engine of the present invention, being configured to calculate a knocking occurrence ratio (SEV) which is a ratio of a cycle number of cycles in which a predetermined knocking occurs for a period of the cycles of the predetermined cycle number, to the predetermined cycle number, decide a target value of an ignition timing of the ignition device based on a deviation (ΔSEV) between an occurrence ratio delay calculation value (SEV) obtained by performing delay calculation of the knocking occurrence ratio and a predetermined occurrence ratio target value (SEV), and drive the ignition device so that the ignition timing reaches a command value (IGN) decided according to the target value.
