David Adeang is a politician on Nauru. He is a founding member of the Naoero Amo (Nauru First Party), currently the only successful political party on the island.

Adeang began his political career as a lawyer. In the parliamentary elections of May 2003, amidst political and economic turmoil, the Naoero Amo won 3 of the 18 seats, and Adeang was one of the elected members. The Naoero Amo entered a coalition with Ludwig Scotty and his supporters. Scotty became President and Adeang became Finance Minister. He was only finance minister for three months however, as in August 2003 Scotty's government fell, and Kinza Clodumar became finance minister.

In April 2004, Adeang was charged with sedition along with Kieren Keke and Fabian Ribauw after a protest at Nauru's airport. In June 2004 Clodumar and the Naoero Amo united to re-elect Scotty President. Clodumar remained finance minister, while Adeang became Minister of Foreign Affairs and Justice. Also, the charges against Adeang and the others were dropped. His appointment as foreign minister is interesting because he is the first foreign minister not to be the President of Nauru. That post had been given to the President since Nauru gained independence in 1968. Adeang was easily re-elected to Parliament from the Ubenide constituency in the October 2004 electioins. Later that month, he left the position of justice minister, bubecame finance minister, and retains the position of foreign minister.
