Alderney (French: Aurigny; Auregnais: Aoeur'gny) is the northernmost of the inhabited Channel Islands. It is part of the Bailiwick of Guernsey, a British Crown dependency. It is 3 miles (5 km) long and 1 1/2 miles (2.4 km) wide. The area is 3 square miles (8 km²), making it the third-largest island of the Channel Islands, and the second largest in the Bailiwick. It is around 10 miles (15 km) to the west of La Hague on the Cotentin Peninsula, Normandy, in France, 20 miles (30 km) to the north-east of Guernsey, and 60 miles (100 km) from the south coast of Great Britain. It is the closest of the Channel Islands to France and to the United Kingdom. It is separated from Cap de la Hague by the dangerous Alderney Race (French: Raz Blanchard).

The only parish of Alderney is the parish of St Anne, which covers the whole island.

Other settlements include Braye, Crabby, Longis, Mannez, La Banque, and Newtown.

Geology: "The island can be divided into three based on the mapping of Laffoley (Figure 2). To the west is the Western Granodiorite (2,200Ma); in the centre of the island basement rocks have been intruded by the Central Diorite Complex, a series of Cadomian basic to intermediate rocks dated between 600-500Ma, whilst to the east lies the Alderney Sandstone, a feldspathic sandstone of Lower Palaeozoic age. Despite a variety of suitable lithologies, no mineral veins nor metalliferous mineralization have been recorded. (Laffoley 1985b)." (http://www.rosiehardman.co.uk/taxev.htm)
