Dinghai (help·info) (Chinese: 定海区) is a district of Zhoushan City made of 128 islands in Zhejiang province, China. It is based on the larger northwestern half of Zhoushan Island, where it borders Putuo in the east. The district boundary meets that of Daishan County out at sea to the north of the island. Its southwestern boundary intersects the border of Ningbo, also entirely at sea.
