Reay (/reɪ/, RAY; Scottish Gaelic: Ràth, /rˠaː/) is a village which has grown around Sandside Bay on the north coast of the Highland council area of Scotland.

The origin of the name is uncertain, but possibilities include the Gaelic Reidh (a flat place) or Ratha (a fort or enclosure).

The village contains the remains of a far earlier church, dating from the 16th century but on an ancient dedication to St Colman, along with its small, walled graveyard.

[3] The parish includes the hamlets of Fresgoe, Islaud and Shebster, which are close to the boundary between Caithness and the neighbouring county of Sutherland.

The Secretary of State for Environment, Food and Rural Affairs committed to clean up and open oversight of the work on 25 October 2006.

The 13th Laird of Sandside the Duke of Portland took the Government to Court to assert his ownership down to the low watermark of the estate granted by a barony of 1628 and won.

The 19th Laird of Sandside since 1991, Geoffrey Minter, following the radioactive contamination beginning in 1997, took the Government owned UKAEA to court in 2003 and won, beyond appeal, a judicial review in Scotland's highest court proving radioactive damage to the estate's land and the UKAEA to be in breach of its statutory duty under the Nuclear Installations Act.
