RAF Saxa Vord was a radar station operated by the Royal Air Force. It was situated on the island of Unst, one of the Shetland Islands in the north of Scotland. Its radar provided long-range coverage of the airspace to the North of Scotland. The station's motto "Praemoneo de Periculis", Forewarn of Danger, reflected its role.The island of Unst has played an important part in the defence of the UK since the outbreak of the Second World War. By 1945, there were two radar sites in existence — one on Saxa Vord hill, and the other at Skaw on the east coast.

The present station was officially opened on 27 September 1957 as No 91 Signals Unit, and in 1960 was visited by Queen Elizabeth II. In the early days, the site was shared with the Royal Navy which worked in the Admiralty building. In the following years, RAF Saxa Vord was a vital part of Britain's air defence during the Cold War. RAF Saxa Vord consisted of three sites: the domestic site, the technical site and the married quarters called Setters Hill Estate (SHE).

The technical site was originally home to a Type 80 search radar, a Type 14 standby reporting radar and a Type 13 height finder. The Type 80 was unfortunately lost when it was blown out of the radome and down the cliffside. In 1979, there was a 649 search radar (Type 96) and Height Finder 200, and these were planned to be replaced by the Type 93 in the mid 90s as part of the new IUKADGE system. When The type 93 became obsolete a radical new method was tried.

RAF Saxa Vord was a part of the Sector 1 of the UK Air Defence Region (the RAF covering most of NATO Early Warning Area 12, some 750,000 square miles). Sector 1 was the airspace north of the 55th parallel north. Being a Control and Reporting Post(CRP)/ Reporting Post (RP), it passed its radar picture and information (along with RAF Benbecula) to the Sector Operations Centre (SOC /CRC) RAF Buchan, which also received information from the Danish site on the Faroe Islands.

From around 2000 until 2 April 2004, the station operated as RRH Saxa Vord, an unmanned Remote Radar Head operated from a parent station (RAF Buchan). On 2 April 2004, RAF Saxa Vord was upgraded from a Remote Radar Head to a full manned station, taking over control of the radar defences in the area. RAF Buchan will be downgraded to a Remote Radar Head. RAF Saxa Vord was closed and put on a 'care and maintenance' basis in April 2006.

RAF Saxa Vord was further north than Leningrad, and on the same latitude as Anchorage, Alaska. The station was named after Saxa Vord, which is the highest hill on Unst at 935 ft (285 m). It holds the unofficial British record for wind speed, which in 1962 was recorded at 177 mph (285 km/h) — just before the measuring equipment blew away.
