A lubrication system for an in-wheel motor powertrain is proposed. The system includes a housing having a motor and supporting a wheel, and having a space therein; an input gear and an output gear provided in the housing; two intermediate gears each provided with a first gear meshed with the input gear, and a second gear meshed with the output gear and having a pitch circle diameter different from that of the first gear, the first and second gears being integrally and concentrically coupled together; a pump gear meshed with the input gear; a bearing plate rotatably supporting the input gear, the output gear, and the intermediate gears; a cover plate configured to provide a part of a lubrication pump driven by the pump gear; and a first oil supply part provided by the cover plate and a mid-plate to lubricate the output gear and the intermediate gears.
