A golf ball position marking device enables a user to reliably and unobtrusively mark the position of a golf ball on a putting green. The golf ball position marking device comprises a putting green contact surface, a marker material dispensing port, a marker material dispensing actuator and a marker material reservoir. The putting green contact surface is sized and shaped to permit stable positioning of the golf ball position marking device on a putting green in close proximity to a golf ball on the putting green thereby providing oriented alignment of the golf ball position marking device with the golf ball on the putting green. Activation of the marker material dispensing actuator results in the dispensing of a marker material from the marker material reservoir onto the putting green at a predetermined vector position relative to the point where the golf ball contacts the putting green.
