The invention discloses a novel anti-theft door lock. A button is arranged on an internal handle of a door and is connected with a clutch part. When the internal handle of the door is independently pressed and turned, the clutch part is located outside a clutch hole and accordingly is in idle, and a lock body drive part cannot be driven to rotate for unlocking. The button is required to be pressed while the internal handle of the door is pressed down, the clutch part can enter the clutch hole to rotate, and accordingly the lock body drive part is driven to rotate for unlocking. Lawless persons are effectively prevented from putting tools into the lock through a cat eye from the outside to press down the internal handle of the door for unlocking, and the novel anti-theft door lock has high anti-theft performance.
