A putter-type golf club head that, when oriented in a reference position, includes a striking wall extending in the heel to toe direction and defines a substantially planar striking face for hitting a golf ball. A central elongate member is in communication with, and extends rearward from, the striking wall. An upper surface of the central elongate member includes a plurality of separate alignment elements. At least one of the plurality of alignment elements has an edge that extends substantially parallel to the striking face. The length of the parallel edge is substantially equivalent to the diameter of a golf ball.
