The present invention provides an electrostatic discharge (ESD) protection circuit including an ESD detection circuit and a plurality of power clamp circuits. The ESD detection circuit is electrically connected to a first high power line, a second high power line and at least one low power line, and is used to detect an ESD event occurring in the first high power line and another ESD event occurring in the second high power line. The ESD detection circuit includes a first trigger unit and a second trigger unit, electrically connected to the first high power line and the second high power line respectively. Each power clamp circuit has a trigger node, and the trigger nodes are electrically connected to the first trigger unit and the second trigger unit.
