Jersey ( JUR-zee, French: [ʒɛʁzɛ] (listen); Jèrriais: Jèrri [ʒɛri]), officially the Bailiwick of Jersey (French: Bailliage de Jersey; Jèrriais: Bailliage dé Jèrri), is an island country and self-governing Crown Dependency near the coast of north-west France. It is the largest of the Channel Islands and is 14 miles (23 km) from the Cotentin Peninsula in Normandy. The Bailiwick consists of the main island of Jersey and some surrounding uninhabited islands and rocks including Les Dirouilles, Les Écréhous, Les Minquiers, and Les Pierres de Lecq.Jersey was part of the Duchy of Normandy, whose dukes became kings of England from 1066. After Normandy was lost by the kings of England in the 13th century, and the ducal title surrendered to France, Jersey remained loyal to the English Crown, though it never became part of the Kingdom of England.

Jersey is a self-governing parliamentary democracy under a constitutional monarchy, with its own financial, legal and judicial systems, and the power of self-determination. The island's relationship with the Crown is different from the other Crown Dependencies; the Lieutenant Governor represents the Queen there. Jersey is not part of the United Kingdom, and has an international identity separate from that of the UK, but the UK is constitutionally responsible for the defence of Jersey.The island has a large financial services industry, which generates 40% of its GVA. British cultural influence on the island is evident in its use of English as the main language and Pound sterling as its primary currency. Additional British cultural similarities include: driving on the left, access to British television and newspapers, a school curriculum following that of England, and the popularity of British sports, including cricket. The island also has a strong Norman-French culture, such as its ancient Norman language Jèrriais and place names with French or Norman origins. The island has close cultural links with its neighbouring islands in the Bailiwick of Guernsey. Jersey and its people have been described as a nation.
