Mājuli or Majuli (mazuli) is a river island in the Brahmaputra River, Assam and in 2016 it became the first island to be made a district in India. It had an area of 1,255 square kilometres (485 sq mi) at the beginning of the 20th century, but having lost significantly to erosion it covers 352 square kilometres (136 sq mi) as at 2014. Majuli has shrunk as the river surrounding it has grown. Majuli is since 2004 in the UNESCO Tentative List for nomination as a World Heritage Site.
