Nellaidhoo is one of the inhabited islands of Haa Dhaalu Atoll administrative division and geographically part of Thiladhummathi Atoll in the north of the Maldives.
On Saturday 8 December 1821, an extremely strong cyclone hit Nellaidhoo and many other island of northern Maldives causing severe damage. More recently, in 2006 the government of the Maldives listed Nellaidhoo as one of the islands under significant threat from sea level rise due to global warming.
