Abstract: A locking gate latch includes a latch assembly and a striker bar. The striker bar is attached to a gate frame and the latch assembly is attached to a gate post. The latch assembly includes a latch frame, a lock latch, a locking plate and a locking tongue. The lock latch is pivotally retained by one leg of the latch frame. The locking plate is pivotally retained by the other leg of the latch frame. One end of the locking tongue is attached to an outside key lock and the other end is received by the locking plate. Pivoting the outside key lock to one side locks the locking gate latch. Pivoting the outside key lock to the other side unlocks the locking gate latch. A second embodiment of the gate latch further includes an inside locking assembly, which allows a gate to be locked from an inside.
