Buthidaung (Burmese: ဘူးသီးတောင်မြို့; MLCTS: bu:si:taung mrui., pronounced [búðídàʊɰ̃ mjo̰]) is a town in Rakhine State, in the westernmost part of Myanmar (Burma).

Buthidaung lies on the west bank of the Mayu river, and experienced severe flooding in June 2010 and July 2011.

Buthidaung is situated about 16 miles from Maungdaw, and similarly to this town has no train station or airport.

Buthidaung has a majority Rohingya population, of which many have fled since the 2012 Rakhine State riots.

During the 2016–17 Northern Rakhine State clashes, three police stations in Buthidaung were reportedly surrounded by Rohingya insurgents.
