A purge system for fuel evaporation gas may include an ejector, having a nozzle configured to allow driving fluid to pass therethrough, a driving inlet through which the driving fluid is supplied into the ejector, a suction inlet through which purge gas including a fuel component is drawn as suction fluid from a canister into the ejector, a diffuser outlet through which a mixture of the driving fluid that has passed through the nozzle and the drawn purge gas is discharged out of the ejector, and a suction passage extending from the suction inlet toward a downstream side of the nozzle based on a flow direction of the driving fluid, and a bypass passage coupled from the suction inlet to the driving inlet.
