The Shire /ʃiːrɛ/ is the largest river in Malawi. The river has been known as the Shiré or Chire River. It is the only outlet of Lake Malawi and flows into the Zambezi River in Mozambique. Its length is 402 kilometres (250 mi). The upper Shire River issues from Lake Malawi and runs approximately 12 miles before it enters shallow Lake Malombe. It then drains Lake Malombe and flows south through Liwonde National Park where large concentrations of hippopotamus are common along its shores.
