Ros Mey (June 30, 1925 – December 12, 2010) was a Cambodian-born American Buddhist monk and survivor of the Khmer Rouge regime.

Mey was the Chov Atika, or head monk, of Wat Thormikaram, the first ethnic Khmer Buddhist temple in the United States, which is located in Providence, Rhode Island.

He was the fifth child born to Ouch Mey (his father) and Soeum Mon (his mother), having four older sisters and a younger brother.

Mey originally worked as a land surveyor for the Cambodian government until the Khmer Rouge took power in 1975, establishing Democratic Kampuchea.

In 1993, Ros Mey was ordained a Buddhist monk at the Wat Thormikaram temple in Providence, Rhode Island, when he was 62 years old.
