Hongkou (ⓘ; formerly spelled Hongkew) is a district of Shanghai, forming part of the northern urban core.

[1] The district borders Yangpu to the east, Pudong to the southeast, Huangpu to the southwest, Jing'an to the west and Baoshan to the north.

It is the location of the Astor House Hotel, Broadway Mansions, Lu Xun Park, and Hongkou Football Stadium.

During the Tang dynasty, the area in modern Hongkou District may have been a beach included in a seawall (捍海塘) near the East China Sea.

[3] 20,000 Ashkenazi Jewish refugees from Nazi-occupied Europe lived in an overcrowded square-mile section known to as the Shanghai Ghetto, in the Tilanqiao neighborhood of Hongkew.
