The present invention relates to a pulsation reduction apparatus of a hydraulic piston pump, comprising: a block housing that has one end connected to the first hydraulic circuit and the other end connected to the second hydraulic circuit; a damper that is embedded in the block housing, absorbs pressure resulting from working fluid introduced to the first hydraulic circuit, assists with pressure increase of the second hydraulic circuit, and allows shape deformation; and viscosity damping units that are embedded in the block housing, are arranged between the first hydraulic circuit and the damper and between the second hydraulic circuit and the damper, and reduce viscosity of the working fluid introduced from the first and second hydraulic circuits, thereby reducing pressure pulsation and stably performing shock absorption and pressure increase at the same time with a relatively simple configuration.
