Qiu Chuji (10 February 1148– 22 August 1227), courtesy name Tongmi (通密), also known by his Taoist name Master Changchun, was a renowned Taoist master from late Southern Song/Jin dynasty and a famous disciple of Wang Chongyang, the founder of Quanzhen School. He is known for being invited by Genghis Khan to a personal meeting near the Hindu Kush, who also respected and honored him as an Immortal.

Qiu is one of the Seven Perfected of the North. He is the founder of the Longmen (Dragon Gate) school of Quanzhen Taoism which already at his time became the most widespread school of Taoism, so prominent that it became synonymous with the phrase "the Dragon Gate covers half the realm", and it is still the case nowadays.
