Jiji (Chinese: 集集; pinyin: jíjí; Wade–Giles: Chi-chi; Pe̍h-ōe-jī: Chi̍p-chi̍p) or Chichi is an urban township located in the west central portion of Nantou County, Taiwan. In the past, the Jiji township encompassed a much larger area and included the present-day Shueili Township, but today's Jiji is the smallest of Taiwan's townships by area.
