Alderney (French: Aurigny; Auregnais: Aoeur'gny) is the most northerly of the Channel Islands and a British Crown dependency and part of the Bailiwick of Guernsey. The island is five kilometers (3 mi) long and two and a half kilometers (1.5 mi) wide for a total area of eight square kilometers (3 sq.mi). Alderney is around sixteen kilometers (10 mi) from France, thirty two kilometers (20 mi) to the north-east of Guernsey and ninety-seven kilometers (60 mi) from the south coast of England. Alderney is separated from Cap de la Hague by the dangerous currents of La Raz.

Alderney has a population of 2400 people, and they are traditionally nicknamed vaques after the cows, or else lapins after the many rabbits seen in the island.   The only parish of Alderney is the parish of St Anne which covers the whole island.

The main town, St. Anne, features an imposing, pretty church and a cobbled high street. There is a primary school, a secondary school, and a post office as well as hotels, restaurants, banks and shops.
