A foldable window blind includes a cord-winding device, a foldable curtain suspended from the cord-winding device, two vertical rows of positioning members, and a counterweight device. The cord-winding device includes a rail, a spool unit, and two pull cords suspended from the rail and biased to be wound on the spool unit. Each of the positioning members is sleeved movably on a corresponding one of the pull cords, and is fastened to the curtain. The counterweight device is fastened to a lower end of the curtain, and is movable upwardly to an upper limit position so as to fold the curtain to form a plurality of curtain folds. When the counterweight member is disposed at the uppermost position, a lower end of the counterweight device is located below lower ends of the curtain folds.
