A table tennis training system including a pitching machine and a cage spaced around the pitching machine at the back, the pitching machine includes a machine base defining a vertical ball channel, a shooting box pivotally mounted on the machine base at the top and defining a storage chamber. A blowing fan is arranged to blow ping-pong balls from the ball channel into the storage chamber. A ball feeding mechanism guides table tennis balls from the storage chamber to a firing position one after another, and a pitching mechanism is moved between a left limit position and a right limit position and controlled to throw the table tennis ball from the firing position. The pitching mechanism includes two rotary members and two unidirectional motors separately controlled to turn the rotary members for driving the table tennis ball from the firing position out of the shooting box.
