The Royal Ranger Regiment (; RRD) is an infantry regiment of the Malaysian Army. Although it is second in seniority to the Royal Malay Regiment (Rejimen Askar Melayu DiRaja; RAMD), the RRD can trace its origins back to the mid 19th century and the establishment of The Sarawak Rangers, the peacekeeping force in the Sarawak region. This force was absorbed by the Sarawak Constabulary in 1932, but the name was revived in 1941 as a British Colonial unit; this unit commanded by British Lieutenant Colonel C.M. Lane was captured by the Japanese in 1942.
