Jiaozhou Bay (simplified Chinese: 胶州湾; traditional Chinese: 膠州灣; pinyin: Jiāozhōu Wān; German: Kiautschou Bucht) is a bay located in the prefecture-level city of Qingdao (Tsingtau), Shandong Province, China.
Huangdao District (Chinese: 黄岛区; lit. 'Yellow Island District') and West Coast New Area (Chinese: 西海岸新区), is a district and a state-level new area of Qingdao, Shandong, China, located south-west and west of the main urban area of the city on the western shore of Jiaozhou Bay. It was identical to Qingdao Economic and Technological Development Zone (QETDZ, simplified Chinese: 青岛经济技术开发区; traditional Chinese: 青島經濟技術開發區; pinyin: Qīngdǎo Jīngjì Jìshù Kāifā Qū), which was launched in 1985 after the zone was merged with Huangdao District and set up the Free Trade Zone in 1992. In December 2012, Jiaonan, a county-level city in Qingdao was merged into Huangdao District.
The pillar industries engaged in the zone include electronics, household electric appliances, building materials, petrochemicals, machinery and pharmaceutical drugs. It is connected via Qingdao Jiaozhou Bay Bridge.
The Kiautschou Bay Leased Territory (German: Deutsches Pachtgebiet Kiautschou), also known as the Jiaozhou, Kiaochau, Kiaochow, Kiauchau, and Kiao-chau Bay Concession, was a German leased territory in Imperial and Early Republican China from 1898 to 1914. Covering an area of 552 km (213 sq mi), it centered on Jiaozhou Bay (Kiautschou-Bucht) on the southeastern coast of the Shandong Peninsula. The administrative center was at Qingdao (Tsingtau). It was operated by the East Asia Squadron of the Imperial German Navy. The Russian Empire resented the German move as an infringement on Russian ambitions in the region.
The siege of Tsingtao (German: Belagerung von Tsingtau; Japanese: 青島の戦い; simplified Chinese: 青岛战役; traditional Chinese: 青島戰役) was the attack on the German port of Qingdao (Tsingtao) from Jiaozhou Bay during World War I by Japan and the United Kingdom. The siege was waged against Imperial Germany between 27 August and 7 November 1914. The siege was the first encounter between Japanese and German forces, the first Anglo-Japanese operation of the war, and the only major land battle in the Asian and Pacific theatre during World War I.

Lying across the Shandong Peninsula and looking out to the Yellow Sea, it borders the prefecture-level cities of Yantai to the northeast, Weifang to the west and Rizhao to the southwest. The Jiaozhou Bay Bridge links the main urban area of Qingdao with Huangdao district, straddling the Jiaozhou Bay sea areas.
