Beigang Township or Peikang Township (Chinese: 北港鎮; pinyin: Běigǎng Zhèn; Pe̍h-ōe-jī: Pak-káng-tìn) is an urban township in Yunlin County, Taiwan. The Beigang River borders the town on the east and south.
During the Dutch era, Ponkan (笨港) was an important coastal castle. In 1621, "Chinese Peter" (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.
