The workpiece centering apparatus is capable of highly reducing damage of a workpiece. The workpiece centering apparatus comprises: a guide plate being provided in a tray and covering a water inlet so as to horizontally introduce water into the tray; and at least three overflow outlets for overflowing the water from the tray, the overflow outlets being formed in a peripheral wall of the tray and arranged in the circumferential direction at regular intervals. The workpiece, which is horizontally fed on a surface of the water stored in the tray, is received and floated by surface tension of the water. Then, the workpiece is centered in the tray by water flows radially overflowing from the tray via the overflow outlets.
