Map - Hsinchu City (Hsinchu)

Hsinchu (, Chinese: 新竹, Pinyin: Xīnzhú, Wade–Giles: Hsin¹-chu²) is a city located in northwestern Taiwan. It is the most populous city in Taiwan Province, not among the special municipalities, with estimated 450,655 inhabitants. Hsinchu is a coastal city bordering the Taiwan Strait to the west, Hsinchu County to the north and east, and Miaoli County to the south. Nicknamed the Windy City for its strong northeastern monsoon during the autumn and winter seasons.

The area was originally settled by the Austronesian Taiwanese indigenous peoples, with the settlement being named "Tek-kham" by the Hoklo immigrants. The city was founded by Han Chinese settlers in 1711, and renamed to its current form in 1878. During the Japanese Era, the city was the seat of Shinchiku Prefecture, named after the city. The prefecture encompassed present-day Hsinchu City and County, as well as entire Taoyuan and Miaoli. After the ROC rule in 1945, the urban area of Hsinchu was organized as a provincial city.

In 1980, the Taiwanese government established the Hsinchu Science Park, a major industrial park, a significant centre for semiconductor manufacturing, industrial and computer technology development. The park contributes a major proportion of Taiwan's GDP. This made Hsinchu a vital economic hub for its economy; the headquarters of TSMC, world's largest independent semiconductor foundry, and United Microelectronics Corporation, are both located in the park.

Besides its industry, Hsinchu is also an important cultural center of Taiwan. The Chenghuang Temple of Hsinchu, built during the Kingdom of Tungning, is a common prayer destination. The research institutions of National Yang Ming Chiao Tung University and National Tsing Hua University are both located near the science park.

Hsin-chu is the Wade-Giles romanization of the Mandarin pronunciation of the Chinese name. The same name is rendered Xīnzhú in Hanyu Pinyin and Sinjhú in Tongyong Pinyin.

This name refers to the settlement's original Hokkien name Tek-chhàm, meaning "bamboo barrier". The name may transcribe an aboriginal name meaning "Seashore". The same name is variously recorded as Teukcham, Teuxham, Tekcham, and Teckcham; its Mandarin pronunciation appears as Chuchien.

Hsinchu is popularly nicknamed "The Windy City" for its windy climate and "The Garden City of Culture and Technology" by its tourism department.
