A lubricant supply system, for a drive apparatus of an electrically operated vehicle having at least one electric machine which outputs power to at least one vehicle wheel via a gear mechanism arrangement, includes an electric machine hydraulic circuit in which a lubricant tank is connected via a suction line to a pressure pump which conveys lubricant to the electric machine via an electric machine supply line, and includes a gear mechanism hydraulic circuit, via which lubricant can be conveyed to the gear mechanism arrangement. The pressure pump is associated as a common pressure pump with both the electric machine hydraulic circuit and the gear mechanism hydraulic circuit so that lubricant during pump operation can be recirculated both in the electric machine hydraulic circuit and in the gear mechanism hydraulic circuit.
