A cigarette lighter which has a safety locking device utilizing a spring biased latch. The cigarette lighter comprises a case, a top cover hingeably attached to an upper part of the case, a lighter seat, a press-down button, and the safety locking device. The latch is slidable mounted on top of the press-down button of the cigarette lighter. The latch is biased by an internal coil spring, which urges the latch to be engaged with the lighter seat, thereby preventing the press-down button from being pressed-down. When a user intends to use the cigarette lighter, the latch can be slid laterally against the spring force of the coil spring to disengage the latch from the lighter seat, thereby allowing the press-down button to be pressed down and ignite the cigarette lighter. Once the user releases the press-down button, it returns upwardly while the latch is biased back by the coil spring and automatically engages with the lighter seat again and thereby locks the press-down button.
