Aurigny Air Services Limited, commonly known as Aurigny, is the flag carrier airline of the Bailiwick of Guernsey with its head office next to Guernsey Airport in the Channel Islands, and wholly owned by the States of Guernsey since nationalisation in 2003. It operates regular passenger and freight services to the Channel Islands, France, the Republic of Ireland and the United Kingdom. Its main base is situated next to Guernsey Airport, with other aircraft and crew based at Alderney Airport. Aurigny is one of the longest serving regional airlines in the world, and is the second oldest established airline in Britain after Loganair. The origin of its name lies in the cognate across Norman languages for Alderney.

A flag carrier is a transport company, such as an airline or shipping company, that, being locally registered in a given sovereign state, enjoys preferential rights or privileges accorded by the government for international operations.
