Abstract: A one way animal gate for easy passage of animals in one direction through the gate and for prevention of passage of the animals in the opposite direction. The one way animal gate includes a pair of doors or a single door hinged to a frame, one or more spring elements for normally urging the doors or door to their closed positions, and a stop for preventing movement of the doors or door beyond a desired position to prevent movement of the animals in an undesired direction. The one way animal gate is placed in an opening in a fence line dividing a pasture, paddock or the like.
