Sandaun Province is the north-westernmost province of Papua New Guinea. It covers an area of 35,920 km² and has a population of 248,411 (2011 census). The capital is Vanimo. In July 1998 the area surrounding the town Aitape was hit by an enormous tsunami caused by a Magnitude 7.0 earthquake which killed over 2,000 people.
The province was governed by a decentralised provincial administration, headed by a Premier, from 1978 to 1995. Following reforms taking effect that year, the national government reassumed some powers, and the role of Premier was replaced by a position of Governor, to be held by the winner of the province-wide seat in the National Parliament of Papua New Guinea.
