The invention discloses magnetic therapy cupping glass which comprises a cupping glass body. A magnetic therapy body which is of a regular polygon structure is arranged in the cupping glass body, annular grooves are formed in the edge of a cupping glass opening of the cupping glass body, and an air pipe is arranged at the top of the cupping glass body, provided with a switch valve and communicated with the interior of the cupping glass body. According to the magnetic therapy cupping glass, magnetic therapy healthcare can be uniformly conducted on a human body through the magnetic therapy body, air in the cupping glass body can be exhausted through the air pipe, therefore, negative pressure can be formed in the whole cupping glass body, and then the cupping glass body is sucked on the skin of the human body; external air can be introduced into the cupping glass body by switching on the switch valve, therefore, the cupping glass body can be conveniently taken down, and no strong pain feeling can be generated.
