A lock for a trailer hitch is disclosed. The locking device is a substantially spherical member dimensioned to fit within the socket of a ball and socket-type trailer hitch. When a trailer tongue is detached from the ball on a towing vehicle, an unauthorized party may connect the trailer to a towing ball on another vehicle and steal the trailer and any property attached to or supported by the trailer. The present invention provides a locking device that lockingly engages the socket in a detached trailer hitch thereby occluding the socket and preventing the attachment of a towing ball thereto until the locking device is removed from the socket by an authorized party with the use of a key.
