Self-locking parcel delivery box is a container with a special locking mechanism that allows a hinged lid to remain unlocked and openable while the container is empty but then automatically lock shut after a package or parcel has been placed inside and the hinged lid is closed. Special locking mechanism comprises, among other things, a rotating striker plate that remains in a closed position while container is empty but then rotates to an open position when a package or parcel is placed inside container. With rotating striker plate in the closed position, a latch cannot extend outward to latch or lock into a latch window when the hinged lid is closed, thereby keeping hinged lid unlocked and openable. With rotating striker plate in the open position, the latch will latch or lock into the latch window when the hinged lid is closed, thereby allowing hinged lid to lock shut.
