An anti-theft coupler device obstructs a trailer hitch coupler to prevent undesired coupling to the tow ball of a towing vehicle. The device comprises a lock body cooperating with and obstructing front and rear facing portions of a trailer hitch coupler, a ball coupler having a resilient, smooth circular face for receipt by the trailer hitch coupler, a locking pin that locks the coupler device to the trailer hitch coupler, and a lock device for preventing access to the locking pin and the ball coupler. The lock body has upright sides with one upright side having an aperture aligned with the trailer hitch coupler for receiving the locking pin, such that the coupler device cooperates with the trailer hitch coupler to prevent undesired coupling. The lock device comprises a padlock that prevents access to the lock pin and undesired removal of the lock body from the trailer hitch coupler.
