Ningbo (Chinese: 宁波; pinyin:  Níngbō (help·info); Ningbo dialect:  Nyin-poh/Nyin-pou (help·info)) is a seaport city in the northeast of Zhejiang province, People's Republic of China. Holding sub-provincial administrative status and separate state-planning status, as of the 2010 census, the municipality has a population of 7,605,700 inhabitants, 3,491,000 of whom reside in the urban area which comprises 6 districts. It lies south of the Hangzhou Bay, facing the East China Sea to the east. Ningbo borders Shaoxing to the west and Taizhou to the south, and is separated from Zhoushan by a narrow body of water.

The first character in the city's name (宁 or 寧) means "serene", while its second character (波) translates to "waves". Together, the name literally means "Serene Waves". The city is abbreviated Yǒng (甬), after the Yong Hill (甬山), a prominent coastal hill near the city, like the Yong River (甬江) that flows through Ningbo. The abbreviation Ning is used more commonly for Nanjing.

It was once named "明州" (Míngzhōu). The character Ming (明) was composed by two parts, representing two lakes inside the city wall, i.e., the Sun Lake (日湖) and the Moon Lake (月湖), but only Moon Lake remains.
