Apparatus and method for de-cocking a crossbow. The apparatus includes: (a) a body adapted to attach to a crossbow, the body having a channel therethrough and a threaded bore therethrough intersecting with the channel; (b) a notched wedge adapted to slide through the channel; and (c) a threaded stud so that when the wedge is slid through the channel and the threaded stud is threaded into the threaded bore, the stud can contact the wedge and halt further travel of the wedge through said body. When the body is attached to a cocked crossbow with the bowstring of the bow positioned in the notch of the wedge, the trigger of the crossbow can be pulled to release the bowstring against the wedge and the crossbow de-cocked by unscrewing the stud.
