Ning is the romanisation of the Chinese surnames 寧 Níng and its variant 甯 Nìng.

In 2008, research by the Chinese Office of Public Security estimated that around 710,000 people in China shared the surname 宁, making it the 173rd most common surname in the People's Republic of China.

The descendants of Ji Wei adopted the geographical name of Ningyi as his surname in commemoration of his settlement.

The surname today appears in many areas of China, although there are a notable handful of towns in Guangxi which each have over 10,000 people surnamed Ning, specifically: Yandun, Taiping and Xinxu in Lingshan County, Xiaojian in Pubei County and Nalin in Bobai County.
