The Royal Signals and Radar Establishment (RSRE) was a scientific research establishment within the Ministry of Defence of the United Kingdom, located primarily at Malvern in Worcestershire. It was formed in 1976 in an amalgamation of earlier research establishments including the Royal Radar Establishment (RRE), itself derived from the World War II-era Telecommunications Research Establishment. In 1979 it merged with the Services Electronic Research Laboratory (SERL) formerly at Baldock and the Signals Research and Development Establishment (SRDE) formerly at Christchurch. There were out-stations at the ex-RAF airfields at Defford and Pershore.
