The present invention relates to a geared in-wheel motor capable of having a compact design while having a lightweight structure compared to the prior art. According to an embodiment of the present invention, a geared in-wheel motor comprises: a circular rim where the tire wraps around an outer ring and is combined; a shaft connected through the center of the rim; a motor assembly including a stator connected and fixed to the shaft from the inside of the rim, and a rotor disposed to surround the stator and rotating; a cover coupled to seal an open portion of the rim; and a gear assembly disposed inside the rim to reduce rotation of the rotor. The gear assembly includes: a sun gear co-centric with the rotor; and a plurality of planetary gears positioned to surround the periphery of the sun gear and fixed to the rotor to rotate together with the rotor.
