A liquid discharge apparatus includes a liquid discharge head, a pump, tanks, a supply path, liquid supply regulators, a pressure detector, and control circuitry. The liquid supply regulators are provided for each of the tanks and configured to open and block the supply path to regulate supply of a liquid from the tanks to the liquid discharge head. The pressure detector is disposed between the liquid supply regulators and the liquid discharge head in the supply path. The control circuitry is configured to determine a low level tank among the tanks on basis of opening and closing conditions of the liquid supply regulators in a case where the pressure detector detects that a pressure of the supply path is lower than a predetermined value, and control the liquid supply regulators to supply the liquid from at least one tank of the tanks to the liquid discharge head.
