An organizer liner (10, 10') is provided for use in a vehicle cargo compartment. The liner has a flexible bottom (15) conforming generally to the shape of the cargo compartment floor, and preferably one or more of rear, side and front rigid elements (20, 30), preferably at least some of which generally conform to walls of the cargo compartment. The rigid elements preferably comprise storage means such as cup holders, trays, bins, insulated coolers, soda or water/milk jug holders, storage boxes with or without lids, or storage wells. Optional partition dividers (50, 60, 60', 60'', 70) may be provided. The dividers include at least one long reinforced divider (50, 70) between opposite walls of the liner, and optionally at least one short divider (60, 60', 60'') between the long divider and a wall of the liner, or between two long dividers.
