Migyitun (Tibetan: ཀློ་མི་ཁྱིམ་བདུན, Wylie: klo mi khyim bdun, THL: lo mi khyim dün), also called Tsari or Zhari (Chinese: 扎日乡), is a town in the Lhöntse County of Tibet's Shannan Prefecture. It is on the banks of the Tsari Chu river close to the McMahon Line, the de facto border with India's Arunachal Pradesh. It is also a key part of the Buddhist Tsari pilgrimage, made once in twelve years, that makes a wide circumambulation of the Dakpa Sheri mountain.
