A corral apparatus has mounting brackets for securing at spaced locations on a wall of a vehicle, livestock trailer, or building, a pair of side panels each having a first end pivotally connected to a respective bracket, and an end panel pivotally secured between the second ends of the side panels, whereby the apparatus can be pivoted between an operative condition in which each side panel extends transverse to the surface and the end panel extends between the ends of the side panels, and a storage position in which the panels are folded flat against one another and the surface. The side panels are adjustable in length to vary the size of the coral.
