Suzhou Creek (also called Wusong River) is a river in China that passes through the Shanghai city centre. It is named after Suzhou, a city in neighbouring Jiangsu province which was the predominant city in this area prior to the rise of Shanghai as a metropolis.

One of the principal outlets of Lake Tai, Suzhou Creek has a length of 125 km, of which 54 km are within the administrative region of Shanghai and 24 km within the city's highly urbanized parts. The river flows into the Huangpu River at the northern end of the Bund in Huangpu District.

Suzhou Creek has played an important role for being the demarcation line between political spheres of influences throughout Shanghai's history. After the Treaty of Nanjing forced China to open up in 1842 and Shanghai became an international trade port, the river formed the boundary between the British concession (Southern bank) and the American settlement (Northern bank) until both concessions were merged into the International Settlement in 1863. When the Japanese invaded Shanghai in 1937, the river formed the boundary between the International Settlement (South) and the Japanese concession (North).

Suzhou (Chinese: 苏州; pinyin: Sūzhōu; Suzhou dialect: [səu tsøʏ]), previously transliterated as Su-chou, Suchow, and Soochow, is a major city located in the southeast of Jiangsu Province in Eastern China, located adjacent to Shanghai Municipality. The city is situated on the lower reaches of the Yangtze River and on the shores of Taihu Lake and is a part of the Yangtze River Delta region. Administratively, Suzhou is a prefecture-level city with an urban population of over 4 million expanding to over 10 million in the administrative area.

Originally founded in 514 BCE, Suzhou has over 2,500 years of rich history, and relics of the past are abundant to this day. The city's canals, stone bridges, pagodas, and meticulously designed gardens have contributed to its status as one of the top tourist attractions in China. Since the Song Dynasty (960-1279), it has also been an important centre for China's silk industry. The classical gardens in Suzhou were added to the list of the UNESCO World Heritage Sites in 1997 and 2000. Suzhou is often dubbed the "Venice of the East" or "Venice of China".
