A drawer partition includes a molded, one-piece, plastic tray with a base wall and upstanding side walls. The side walls have laterally aligned and longitudinally spaced-apart dovetail-shaped grooves in the inner surfaces thereof slidably mateable with dovetail-shaped tongues at the ends of divider panels for dividing the tray into compartments. Pairs of ribs define slots on the side walls to receive end edges of the divider panels. Pairs of flexible legs on the bottom edge of the divider panel are snap-fitted into apertures in the base wall to lock the divider panels in place. The bottom outside edges of the side walls have longitudinal grooves mateable respectively with the upper edges of the side walls of another partition to facilitate guided longitudinal relative sliding movement of stacked partitions. Each tray has front and rear end portions which respectively have recessed outer and inner surfaces to permit overlapping nesting of the ends of longitudinally aligned partitions.
