A winch and cable driven pipe snubbing apparatus which includes a stationary body and a travelling body. The stationary body is adapted to be affixed onto a well head and has at least one pair of spaced apart rotatably mounted pulleys. A first set of slips is positioned on the stationary body. The travelling body is disposed above the stationary body and also has at least one pair of spaced apart rotatably mounted pulleys. At least one winch is mounted to either of the stationary body or the travelling body. Cable extends from the winch around one pulley of each of the at least one pairs of pulleys mounted on the stationary body and around one pulley of each of the at least one pairs of pulleys mounted on the travelling body. The winch draws in cable to pull the travelling body vertically downward toward the stationary body, thereby forcing pipe into the well head.
