Yin Yin Oo

Yin Yin Oo (ယဉ်ယဉ်ဦး) is a Burmese diplomat and a member of the Advisory Board of the State Administration Council (Myanmar's governing military junta). Referring to her service in the military government of ruler Min Aung Hlaing, The Irrawaddy called her one of "the accomplices of Myanmar's murderer-in-chief". She previously served as the deputy director-general of International Organizations and Economic Department of the Foreign Ministry of Myanmar under President Thein Sein. She retired in 2016 before Aung San Suu Kyi took office. She is the daughter of former president Maung Maung.

On 9 February 2009, leaked diplomatic cables reported on a meeting between US diplomats and Yin Yin Oo, where she advocated for improving Myanmar-United States relations through anti-narcotics cooperation and recovery of US remains from World War II.
