Arfon is a constituency of the House of Commons of the Parliament of the United Kingdom (at Westminster). Although the constituency is relatively large by geographical area, it is a predominantly urban rather than rural seat, with the majority of the population living in the two towns on which the constituency is based, Bangor and Caernarfon. "Arfon" is a historical name for the area, meaning "facing Anglesey"; it is also the name of the former district council. This seat was created by the Welsh Boundary Commission in time for the 2010 general election, and replaced the old seat of Caernarfon. Bangor was in the old seat of Conwy. The same boundaries were used for the Arfon Welsh Assembly constituency in the 2007 Welsh Assembly election.
