The invention provides a hydraulic jack which comprises a base serving as a carrier for installing other components. The inner cylinder barrel is vertically fixed on the base, and a sliding cavity is formed in the inner cylinder barrel; the outer cylinder barrel is vertically matched outside the inner cylinder barrel in a sliding manner; the valve plug assembly is arranged in the sliding cavity in a sliding fit mode, the sliding direction of the valve plug assembly is parallel to the axis direction of the inner cylinder barrel, and the valve plug assembly is in rigid connection with the outer cylinder barrel through a valve plug rod and can slide synchronously with the outer cylinder barrel. The valve plug driving assembly is mounted on the outer cylinder barrel and is used for driving the valve plug assembly to slide up and down; and the supporting component is mounted on the side wall of the outer cylinder barrel in an up-down adjustable manner and is used for supporting a lifted object. The hydraulic jack is compact in structure, high in strength, high in loading capacity, long in stroke and safe and reliable to use.
