The invention relates to a lubricant supply system for a drive unit of an electrically operated vehicle, comprising at least one electric machine (1) which acts via a transmission arrangement (7) on at least one vehicle wheel, an electric machine hydraulic circuit (E) in which a lubricant tank (25) is connected via a suction line (27) to a pressure pump (29) which conveys lubricant (31) via an electric machine supply line (59) into the electric machine (1), and a hydraulic transmission circuit (G), via which lubricant (31) can be conveyed into the transmission arrangement (7). According to the invention the pressure pump (29) as a common pressure pump is associated with both the electric machine hydraulic circuit (E) and also with the transmission hydraulic circuit (G), so that during pump operation lubricant (31) can be circulated both in the electric machine hydraulic circuit (E) and also in the transmission hydraulic circuit (G).
