Port of Yingkou, International seaport in Liaoning Province, China

Port of Yingkou is an international seaport in Yingkou, Liaoning, with two dockland areas: the old port at the mouth of the Daliao River and the Bayuquan port on Liaodong Bay. It has 27 shipping berths and handles grain, sugar, timber, oil tar, coal, steel, minerals, vehicles and up to 250,000 containers a year.

River and coastal trade at Yingkou dates to 1280, but international shipping began in 1858 when the Treaty of Tianjin designated it a treaty port. The first dock opened at the Liao River mouth in 1864, followed within a decade by docks at the Hun and Tai mouths, forming the old port. After the treaty lapsed, shipping declined until the reforms of the late 1970s led to construction of Bayuquan Port on Liaodong Bay.

The name Yingkou derives from "Meigouying", a tidal ditch that emptied at low tide and submerged at high tide, as recorded in the Dong Sansheng Jilue. The Tianhou Temple on West Street, founded in 1726, served the sailors and traders; a Daoguang-era stele records boats gathering in the thousands daily.

The port has two separate dockland areas: the old port at the mouth of the Daliao River and Bayuquan port on Liaodong Bay. The Bayuquan container terminal, developed with COSCO from 1996, handles up to 250,000 TEU a year. Cargo operations are industrial, so visitors should view the docks from public waterfront areas rather than expect tours.

The old port grew from docks opened at the mouths of the Liao, Hun and Tai rivers in the decade after 1864. In November 2016 the port group agreed a partnership with Russian Railways and took a 49% stake in the Bely Rast terminal logistics centre in Russia.
