A dry fire prevention safety mechanism for crossbows having a trigger mechanism which releases a bowstring to discharge an arrow. A spring-loaded catch arm is pivotally connected to the crossbow and has a hook at one end and a ramp portion at the opposite end which extends into an arrow seating well. When an arrow is positioned to be discharged, the ramp portion is abutted by the arrow which disengages the hook from the trigger and enables operation of the crossbow.
