Zaifeng, also known as Tsai Feng, Prince of Ch'ün, formally known by his title Prince Chun, was a Manchu prince and regent of the late Qing dynasty. He was a son of Yixuan, the seventh son of the Daoguang Emperor, and the father of Puyi, the Last Emperor. He served as prince regent from 1908 to 1911 during the reign of his son until the Qing dynasty was overthrown by the Xinhai Revolution in 1911.

Prince Chun of the First Rank, or simply Prince Chun, was the title of a princely peerage used in China during the Manchu-led Qing dynasty (1644–1912). It was also one of the 12 "iron-cap" princely peerages in the Qing dynasty, which meant that the title could be passed down without being downgraded.
