The Hemudu culture (5500 to 3300 BCE) was a Neolithic culture that flourished just south of the Hangzhou Bay area in Jiangnan in modern Yuyao, Zhejiang Province. The culture may be divided into early and late phases, before and after 4000 BCE respectively.

The Hemudu people lived in long, stilt houses. Communal longhouses were also common in Hemudu settlements. The Hemudu were one of the earliest cultures to cultivate rice. Scholars view the Hemudu culture as a source of many proto-Austronesian cultures.
