A low-noise pocket-type wheel guard is provided and includes a guard that is installed to face a surface of a tire in a vehicle, in which a noise reduction pocket is formed to protrude toward an interior of the vehicle in the guard. Since the noise reduction pocket is formed on the end portion of the wheel guard, in which a sound field is expected to be formed due to tire pattern noise, formation of a sound field due to the tire pattern noise is disturbed and prevented.
