Beigang, Hokkō or Peikang is an urban township in Yunlin County, Taiwan.

During the Dutch era, Ponkan (Chinese: 笨港; Pe̍h-ōe-jī: Pùn-káng) was an important coastal castle.

[4] In 1621, Pedro Yan Shiqi (顏思齊) from Zhangzhou, Fujian and his forces occupied Ponkan (modern-day Beigang) and started to develop Tsulosan (諸羅山; today's Chiayi City), which grew to become the capital of Tsulo County in 1704.

The township comprises 28 villages: Caohu, Dabei, Datong, Fupan, Fuzhao, Gongguan, Gongrong, Gouzao, Guangfu, Guangmin, Haoshou, Hougou, Huasheng, Liucuo, Nanan, Pangou, Renan, Renhe, Shuipu, Shujiao, Sifu, Tunghua, Tungyang, Xincuo, Xinjie, Xishi, Yimin and Zhonghe.

Beigang is only a short drive (approximately fifteen minutes by car) from National Chung Cheng University, one of Taiwan's foremost research universities.
