Remote Radar Head Trimingham or RRH Trimingham is a former TPS-77 radar station situated on the coast in the English county of Norfolk. The site is located on the coast road between Cromer and Mundesley, 1 kilometre east of the village of Trimingham but the activity has now moved to RRH Neatishead due to the threat from coastal erosion. The radar station was a satellite station of RAF Neatishead. This radar station was controlled and maintained by a section of Radar Technicians and Operators and supported by a team of Ground Engineers. Trimingham provided extensive coverage of the East coast of the United Kingdom and helped contribute to the recognised air picture and defence of the United Kingdom. The type 93 became operational on the site in April 1997.

Trimingham is a coastal village and a civil parish in the North Norfolk district of Norfolk, England.
