Binzhou (Chinese: 滨州, bin-joe), formerly Putai, is a prefecture-level city in northern Shandong Province in the People's Republic of China. The city proper sits on the northern bank of the Yellow River, while its administrative area straddles both sides of its lower course before its present delta. As of the 2020 Chinese census, its population was 3,928,568 inhabitants (3,748,474 in 2010), and its built-up (or metro) area made of Bincheng and Zhanhua urban Districts was home to 1,188,597 inhabitants.

Human settlement dates to at least the Chinese Neolithic. During the Shang, the area around Binzhou was held by the Pugu, who were counted among the "Eastern Barbarians" or Dongyi. Pugu joined the Shang prince Wu Geng's failed rebellion against the Zhou and was destroyed c. 1039, with its lands given to the minister Jiang Ziya as the march of Qi. The Bamboo Annals suggest the Pugu continued to trouble the Zhou for another decade and state they were again destroyed c. 1026. Qi became one of the most powerful of China's Warring States but was ruled from Yingqiu (modern Zibo), except for a brief hiatus under Duke Hu. He relocated to Bogu but was overcome by the revolting people of Yingqiu; his successor restored the former capital.

The name Binzhou arose under the Five Dynasties period because its land then bordered the Bay of Bohai. The deposition of silt from the Yellow River—which assumed its present course after the disastrous floods of the 1850s—has since moved the site well inland. The city itself was known as Putai into the 20th century, but Putai County was abolished in March 1956 and the name now survives only as the town's Pucheng Subdistrict.

Public works have reduced the destructiveness of the river, permitting Binzhou and neighboring Dongying to be developed into cities. The former Huimin Prefecture (惠民地区) was renamed Binzhou in 1984. It was given city status in 1992. At the end of 2022, the city had a resident population of 3,918,600 people. The major Industries are based on oil (Shengli Oil Field), chemicals, and textiles.

The prefecture-level city of Binzhou administers seven county-level divisions, including two districts, one county-level city and four counties.

Binzhou lies on the alluvial plain formed by the Yellow River. The entire length of countryside around the river from Pucheng Subdistrict to the Bay of Bohai has been created by deposition of sediment since the Qin Dynasty. The present prefecture borders (counterclockwise from due west) Dezhou, Jinan, Zibo, Dongying, the Bay of Bohai, and Hebei.

Binzhou has a monsoon-influenced humid continental climate (Köppen Dwa), with four well-defined seasons. Binzhou is one of the warmest cities in the world with a continental climate, with summers reaching as high as 31 °C, and the average temperature in the city being 13.0 °C. Conditions are warm and nearly rainless in spring, hot and humid in summer, crisp in autumn and cold and dry in winter. More than half of the annual precipitation occurs in July and August alone; snow occasionally falls during winter, though heavy falls are very rare.

Binzhou, and neighboring Dongying, has historically had an agrarian economy. Binzhou is known regionally for its "dongzao" (literally, "winter dates"). After the Shengli Field was discovered, most of the field was incorporated into newly created Dongying, although Binzhou maintain some oil operations. Binzhou has been diversifying its economy away from agriculture by attracting manufacturing and foreign direct investment into the city. Among Binzhou's large businesses are Weiqiao, a textile company, and Binzhou Pride, an automobile company that only lived 2006 until 2008.
