A toy projectile launcher for launching a projectile from a housing having a trigger mounted to the housing which can be depressed to actuate a motor. A mechanical linkage operatively interconnects the motor with an actuator which generates a source of pressurized air upon movement of the actuator from its cocked to its un-cocked position to effect automatic repeated movement of the actuator to its cocked position and release from its cocked position. Repeated intermittent sources of pressurized air are generated for sequential launching of projectiles. Disclosed embodiments also include a toy projectile launcher having an air passageway through which compressed air is passable to a plurality of sequential projectile holders holding respective projectiles to be launched. The projectile holders are advanced into operative launching engagement with the air passageway sequentially by an advancing mechanism.
