An adjustable golf ball tee for teeing up a golf ball in a playing field includes an elongated support provided with a golf ball support surface and a base at opposite ends. The base is received in the cavity of a receiver housing which supports a nut member to threadably receive the threaded portion of a screw. The head portion of the screw is integrally surrounded by plastic material comprising the base of the golf ball support. The terminal end of the screw is provided with a jam nut that limits the extent at which the screw threads can be withdrawn from the nut in the cavity of the receiver. A cap is fitted onto the lower end of the receiver to prevent the ingress of foreign material and a bevel at the lower end of the receiver anchors it against rotation in a bored hole extending beneath the playing field.
