A tapping apparatus adapted for tapping a workpiece, comprising:

• a lower die unit configured to drive the workpiece to move along a conveying direction;
• an upper die unit disposed above and movable upwardly and downwardly relative to said lower die unit;
• a tapping mechanism disposed between said lower and upper die units and adapted to be driven by said upper die unit for tapping the workpiece so that the workpiece is formed with a tapped hole;
• and
• a thread checking mechanism disposed between said lower and upper die units and spaced apart from said tapping mechanism along the conveying direction, said thread checking mechanism being driven by said upper die unit for checking the tapped hole of the workpiece;
• wherein the thread checking mechanism includes a thread checking drive rod driven and rotated by said upper die unit.
