An elevator door system having a locking apparatus is provided to release the locking state so that a passenger in an elevator can safely escape from the elevator. An elevator door system having a locking apparatus includes a locking bracket(110), a locking bar(130), a resilient member(150), and a fixation roller(170). The locking bar includes a hinge section, a horizontal section, and a locking section. The upper end of the resilient member is engaged with a middle portion of the horizontal section of the locking bar and the lower end thereof is engaged with a hanger frame so that the tip end of the locking bar is disposed so as to be urged to the lower side. The fixation roller is hinge-coupled to a middle portion of a door frame. If the elevator door is closed, the fixation roller is prevented from being arbitrarily opened.
