A wall mounted baseball-style cap holder (or cap clip) that supports the cap the apex of its crown proximate a button (if the cap is so equipped) is described. The clip comprises a base plate including a flat rear surface, which may have a layer of pressure sensitive adhesive attached thereto, and upper and lower spaced arcuate plate-like protrusions that extend generally orthogonally from the base plate. The holder is configured to be mounted to a wall or other substantially vertical surface typically by way of an adhesive or double sided tape, which may or may not be provided with the holder.
