Abstract: A golf hat and golf ball marker assembly containing a hat, a metal strip, and a disc-shaped, metallic golf ball marker. The metal strip is affixed to the side of the hat such as by rivets. Positioned on one side of the strip is a depressed well having a magnetized bottom. The diameter of the well is slightly larger than the diameter of the marker so that the marker fits snugly in place in the web with a very little lateral movement. The depth of the well is slightly less than the thickness of the marker so that the marker extends slightly out of the well for each removal. The marker is held in the well when not in use by virtue of magnetic attraction.
