The National United Party of Arakan (; NUPA) is a political organisation and insurgent group in Rakhine State, Myanmar. It was formed in 1994 as a merger between four nationalist groups, including a faction of the Communist Party of Arakan. Its armed wing was the Arakan Army.
As opposed to the anti-Rohingya Arakan Liberation Army, NUPA/AA was more cordial with the Rohingya and even formed the Arakan Independence Alliance with the Arakan Rohingya National Organisation.
Bangladesh authorities accused NUPA of conducting criminal activities in Chittagong Division.
In 1998, NUPA and Karen National Union leaders were arrested on Landfall Island, India. They were imprisoned in 2010 for allegedly smuggling weapons to Northeast Indian insurgents. On 6 December 2020, NUPA merged with the United League of Arakan.
