Yinzhou District has a long history. As early as the matriarchal commune period of the Neolithic age, there were primitive people living in the territory. In the winter of 1973, the primitive commune site was discovered in lujiaqiao, Sanlian Village, Shenjiao township. It has a history of 5000 years, and its cultural age is equivalent to the second layer of Hemudu culture.

After the Qin Dynasty destroyed Chu, it set up three counties in 222 BC, namely Yin County, Zhen County and jurzhang county.

The Han Dynasty inherited the system of the Qin Dynasty and still set up three counties. In the Eastern Jin Dynasty, Liu Yushu built a new town in Xiaoxi town (now Yinjiang town).

Since then, the territory of Yinxian county has been stable and less changed.

In the past, the city of Ningbo used to be governed by Yin County, formerly known as Mingzhou. In the Ming Dynasty, it was renamed Ningbo as a taboo. After liberation, Ningbo became a city, and Yin county was under the jurisdiction of Ningbo district and Ningbo City.

On April 19, 2002, with the approval of the State Council, it was established as Yinzhou District of Ningbo City.
