Ream Naval Base is a facility operated by the Royal Cambodian Navy on the coast of the Gulf of Thailand in the province of Sihanoukville, Cambodia. The base, which covers approximately 190 acres, is located on a peninsula just southeast of the provincial capital, Krong Preah Sihanouk. In 2010 the base has been the site of some joint Cambodian-United States training and naval exercises under the Cooperation Afloat Readiness and Training (CARAT) program. However in September 2020 one of two US-funded buildings on the base was demolished as the base was being converted by Chinese state-owned enterprises into a major operations hub for People's Liberation Army Navy (PLAN).
