The Majiabang culture (馬家浜文化) was a Neolithic culture that existed at the mouth of the Yangtze River, primarily around the Taihu area and north of Hangzhou Bay in China. The culture was spread throughout southern Jiangsu and northern Zhejiang from around 5000 BC to 3000 BC. Initially, archaeologists had considered the Majiabang sites and sites in northern Jiangsu to be part of the same culture, naming it the Qingliangang culture. Archaeologists later realized that the northern Jiangsu sites were of the Dawenkou culture and renamed the southern Jiangsu sites as the Majiabang culture. The Majiabang culture coexisted with the Hemudu culture for over a thousand years as two separate and distinct cultures, with cultural transmissions between the two cultures.

Majiabang people cultivated rice. At Caoxieshan, a site of the Majiabang culture, archaeologists excavated paddy fields . However, faunal remains excavated from Majiabang archaeological sites indicated that people had domesticated pigs. In addition, the remain of sika and roe deer have been found, showing that people were not totally reliant on agricultural production . Archaeological sites also bear evidence that Majiabang people produced jade ornaments.
