Abstract: A bag holder has a base to be attached to a vertical surface and has two hinged arms to be latched perpendicular to the base in useful positions for holding an open bag. Nestable spaces for the arms are provided within the surface of the base, and hinges connecting the arms to the base permit the arms to be turned from the nestable spaces to the useful positions. The upper edge of each arm is contoured to provide an intermediate upright portion about which a loop, or handle, of a bag is suspended. The arms are biased to be urged to the nestable positions, and latching means between the base and the arms retain the arms in the useful positions.
