A bag dispenser includes a bag platform with a first support surface, a first side, a second side, a first end and a second end. At least one side support extends outwardly from the first and second sides of the bag platform and upwardly from the platform. The at least one side support defines a space sized and shaped to accommodate at least one stack of bags. An overhead mounting feature is attached to the side support and has a series of apertures penetrating the feature for use in attaching to an overhead horizontal surface with at least one fastener. An end panel is pivotally attached to either of the first and second ends of the bag platform. A latching mechanism maintains the end panel in a first, upright position. The latching mechanism is magnetic or includes loop and eye fittings. The dispenser may also have a pivoting side panel.
