The invention relates to a scroll compressor and a lubricating oil supply system thereof. The lubricating oil supply system includes: an oil passage P1 formed by a center hole longitudinally penetrating through the crankshaft; an oil suction port of the oil pump is immersed in the lubricating oil in the oil pool, and an oil outlet of the oil pump is communicated to the oil way P1; an oil passage P3 located in a gap between the upper end surface of the crankshaft and the lower surface of the orbiting scroll; an oil passage P4 formed by a longitudinal hole in the crankshaft, the longitudinal hole extending downward from an upper end face of the crankshaft; and an oil passage P5 formed by a lateral hole in the crankshaft and a gap between the lower edge of the hub of the orbiting scroll and the upper surface of the upper balance weight, the lateral hole extending laterally from the outer peripheral surface of the upper end of the crankshaft to communicate with the longitudinal hole, an opening of the transverse
