Abstract: A cargo bed divider system for a pickup truck includes a first guide rail connectable to a first lateral side of a cargo bed, a second guide rail connectable to a second lateral side of the cargo bed, a cargo bed divider supported between the first guide rail and the second guide rail, and an adjustment mechanism connectable to a forward end of the cargo bed and the cargo bed divider. The adjustment mechanism selectively moves the cargo bed divider between a first position adjacent the forward end of the cargo bed and a second position adjacent to a rear end of the cargo bed.
