An optical pickup actuator which can compensate for a curvature of a disc, an optical pickup employing the optical pickup actuator, and an optical recording/reproducing apparatus employing the optical pickup. The optical pickup actuator includes a base having a holder, a bobbin mounting an objective lens, a plurality of elastic supports having one end coupled to the holder and another end coupled to the bobbin such that the bobbin is movably supported, and a magnetic driving portion which drives the bobbin in a focusing direction and for a tracking direction. The plurality of elastic supports includes inner elastic supports that are positioned on a side of the optical pickup actuator closest to a center of the disc and outer elastic supports that are positioned on an opposite side of the optical pickup actuator closest to an outer perimeter of the disc, and the inner elastic supports and outer elastic supports have different lengths.
