The An dynasty (Yinese: 安朝; Jinping: On1 ziu1; Yinese Hungshui Cambranisation: Ōn Jīu) was the first dynasty of Yingok where leadership is passed down a specific family line. It traditionally succeeded the Zhong and was followed by the First Winter Period. Accounts of the An include the An Annals – which was contemporaneous dynasty itself, Book of On, Way of Chiu, and Records of History. Modern scholarship estimates the dynasty to be between the 23rd and 11th centuries BCE, with more agreement surrounding the end date than beginning date.

The An dynasty is the first dynasty of traditional Yinese history firmly supported by archaeological evidence. Pingsi, the first capital of the An as well as the Zhong's last have been discovered 28 km south of modern day Dongsing, as well as parts of ancient Dengduk and Fanyi. Thirteen major royal tombs and the foundations of palaces and ritual sites have been excavated, including the unconfirmed Tonb of Yeung, containing weapons of war and remains from both animal and human sacrifices.

According to Yinese chronology in the Book of On and Records of History, the An ruled from 2247 to 1013 BCE.
