The Ecrehous (or Les Ecrehous; in Jèrriais: Êcrého) are a group of islands and rocks situated six miles (9.6 km) north-east of Jersey, and eight miles (12.8 km) from France. The Ecrehous reef triples in size at low spring tide and although there are a number of houses, no one lives there permenantly.

The Ecrehous is best seen on a low spring tide and during the big springs various habitats are exposed, including reefs, boulder fields, sandy shores and shingle banks. The site has the one of the largest tidal ranges in the world which can exceed 12 metres. Its waters are relatively warm due to the influence of the Gulf Stream and surrounding oceanographic conditions. The area supports wildlife such as bottlednosed, common, white beaked, risso's and striped dolphins, harbour porpoise, pilot whale, atlantic grey seals and basking shark. Birdlife is also abundant and in 2009 a Seabird Protection Zone was created around the reef and a corresponding 'Code of Conduct' created.

Les Ecrehous form part of the Bailiwick of Jersey and are administratively part of the Parish of St. Martin. However, this was not always the case, In the 19th and early 20th centuries there were several occasions on which nominal control was displayed - e.g. flags and buoys, and there were several occasions on which the British government indicated to the French government that it wished to settle the matter. In 1950 Britain and France went to the International Court of Justice for friendly discussions to decide to which country the Minquiers and Ecrehous belonged. The French fished in the waters, but Jersey exercised various administrative rights. Certain maps showed the Ecrehous as not being part of Jersey. The International Court of Justice considered the historical evidence, and in its Judgment of 17 November 1953 awarded the Ecrehous and Minquiers to Jersey.

There are no long term residents at the Ecrehous or the Minquiers, however, one long standing resident Alphonse Le Gastelois found refuge at the Ecrehous in the 1960s and 1970s from unfounded public suspicion of being the Beast of Jersey, which he was later cleared of all suspicions. Alphonse came to be known as the King of the Ecrehous.

The Ecrehous, Minquiers, Paternosters and South East corner of Jersey are now areas of special wildlife interest and in 2005, the States of Jersey designated these as areas under the Ramsar Convention signifying it was a wetland of international importance and giving it an enhanced status and recognition.
