Abstract: A plurality of panels which are rotatably coupled to each other by sleeves are used to form a portable folding corral for enclosing animals such as horses. The panels may be folded and mounted on a trailer. As a result, the portable folding corral may be easily transported to any site. Each panel has both horizontal and vertical members. Supporting legs slidably fit inside the vertical members and extend below the vertical members to furnish support for the panels. The supporting legs are locked in place by pins which pass through apertures in the legs and vertical members. The corral is rotatably coupled to a vertical support pipe which is fastened to the trailer. After the panels are folded they are placed on top of a horizontal support plate fastened to the trailer. Belts may be used to secure the folded panels to the trailer. A winch or other lifting means may be used to remove the corral from the trailer. In addition, wheels may be used instead of supporting legs.
