A gear shifting apparatus for a multi-speed transmission includes a shifting unit controlling gear shifting by a torque of an actuator and a parking unit controlling a parking state by the torque of the actuator. The actuator includes a control motor transmitting a driving torque to driven gears of the shifting and parking units through a drive gear externally gear-meshed with the driven gears. The shifting unit includes a cam block connected to a first driven gear engaged with the drive gear and having a cam surface on an exterior circumference for shift-stages for controlling gear shifting. In addition, the parking unit includes a parking gear and a parking sprag having an engagement end for controlling engagement and disengagement of a parking state.
