A surfboard fin quick release system, for use on a surfboard having a top surface and a fin having a tang, comprising a fin box submerged within the surfboard and a locking mechanism mounted to the fin tang. The fin box comprises a longitudinal channel having a vertical channel and a horizontal channel. The locking mechanism has a main shaft which extends vertically through the fin tang, a release handle fixed to the main shaft above the fin tang, and a locking base having a locking base flange, said locking base fixed to the main shaft below the fin tang. A coil spring extends around the main shaft between the release handle and the tang. When the fin is extending in the vertical channel, the locking base is selectively positioned by rotating the release handle so that the base flange extends into the horizontal channel to lock the fin within the fin box. The fin may be selectively repositioned along the longitudinal channel by pressing downward upon the release handle, or may be removed from the fin box by pressing downward upon the release handle and rotating said release handle so that the base flange does not extend in the horizontal channel such that the fin may be pulled upward clear of the fin box.
