A putting training device having two alignment guides positioned to extend from the blade of a putter. In one embodiment the alignment guides extend generally parallel to each other to facilitate a generally parallel putting stroke. In an alternative embodiment, each of the alignment guides generally arcuate in shape and extends from the blade of the putter in a generally concentric manner, to facilitate a generally arcuate putting stroke. The ends of the alignment guides are tapered to prevent the alignment guides from catching on the putting surface. Additionally, at least one of the alignment guides is movable, such that the space between the two alignment guides can tailored for the experience level of each user.
