Abstract: A plastic grocery bag support having a base and an upright member, the base and upright members being releasably attached each to the other for the purpose of supporting a plurality of filled plastic grocery bags in a substantially vertical position. The plastic grocery bags are supported on the assembly by means of their integral handles being looped over a shaped upper portion of the upright member. The grocery bags are thereby held in an upright position during transportation thereof. When the upright member is joined to the base member the upright member is held in a position which allows it to have a "zig-zag" horizontal cross section which provides a stiffening characteristic to the complete assembly. Upon release of the upright member from the base member, the two members may be stored in a flat condition in a minimum amount of storage space; the upright member being bendable along a plurality of vertical hinge lines which are formed as an integral part thereof.
