A hydraulic control device for an automatic transmission capable of adjusting the amount of lubricating oil in accordance with a load on a torque converter is provided. A main regulator valve regulates hydraulic oil from an oil pressure source on the basis of a stator reaction force of the torque converter to generate a line pressure for operating engagement of a frictional engagement element. A line pressure switching section switches the line pressure to a low line pressure in a region in which a higher line pressure is not required in response to a driving state of a vehicle, and switches the line pressure to a high line pressure when a target value of an engagement hydraulic oil pressure exceeds a predetermined pressure. A lubricating regulator valve is provided in a lubricating oil passage connected from the main regulator valve to regulate a hydraulic pressure in the lubricating oil passage to a given pressure in response to a driving state of the vehicle. A torque converter regulator valve controls a pressure inside the torque converter. A lubricating shift valve switches between an oil passage for supplying hydraulic oil discharged from the torque converter into the lubricating oil passage and an oil passage for discharging lubricating oil discharged from the torque converter regulator valve.
