David Ranibok Waiau Adeang (born 24 November 1969) is a Nauruan politician, currently serving as President of Nauru.

In April 2004, Adeang was charged with sedition along with Kieren Keke and Fabian Ribauw after a protest at Nauru's airport.

[6] In September 2007, Adeang, as Foreign Minister, made a number of public statements deemed in the United States to be controversial.

[8] This criticism was included in the State Department's report, despite the fact that police, having undertaken an investigation of allegations of wrongdoing, made no attempt to prosecute Adeang.

[11] Subsequently, in March 2008, Adeang was appointed Speaker of the Parliament of Nauru,[12] succeeding Riddell Akua.

On 22 March, Adeang called a Parliamentary session, allegedly without informing government ministers, who therefore did not attend.

Opposition MPs, Adeang included, constituted a majority of legislators present, and passed a ruling outlawing dual citizenship for Members of Parliament.

The ruling, if applied, would affect senior Cabinet ministers Kieren Keke and Frederick Pitcher.

[13] President Marcus Stephen accused Adeang and the Opposition of passing the ruling "after dark on Easter Saturday", "under candlelight".

[21] For its part, the government of Marcus Stephen strongly welcomed the Supreme Court's ruling: whether or not for ideological and principled reasons also, it was seen as ensuring the immediate survival of the Administration.

[22] On 18 April, Stephen declared a state of emergency, dissolved Parliament, and announced fresh elections.

[26] With the death in July 2008 of former President Rene Harris,[27] David Adeang lost an important ally with whom he had closely worked in the earlier part of 2008.

[28] In July, as Waqa was out of the country, Adeang, as acting president, took the controversial decision of banning Nauruan media from broadcasting an interview in which Opposition MP Mathew Batsiua criticised the government's sacking of the chief of police.

Adeang saw to the broadcasting of an interview in which he himself gave the government's position on the agreement, but did not allow the Opposition's view to be aired.
