The invention relates to an anti-theft well lid. The anti-theft well lid comprises a well base and a well lid body which is matched with the well base. The anti-theft well lid further comprises magnetic bars, wherein the magnetic force of the magnetic bars can be started or stopped. The well lid body is provided with a vertical through hole and a transverse through hole, the vertical through hole is formed in the middle of the well lid body, and the transverse through hole is formed between the well base and the vertical through hole. A well base hole corresponding to the transverse through hole is formed in the well base, a magnetic block is arranged in the well base hole, the magnetism of the magnetic block is smaller than that of each magnetic bar, a locking pin shaft is arranged in the transverse through hole, and the locking pin shaft slides in the transverse through hole and the well base hole. The anti-theft well lid is simple in structure and can be opened and closed conveniently and rapidly.
