Gwynedd is a county in north-west Wales, named after the old Kingdom of Gwynedd. Although the second biggest in terms of geographical area, it is also one of the most sparsely populated. A large proportion of the population is Welsh-speaking.
The name Gwynedd is also used for a preserved county, covering the Isle of Anglesey as well as the current county. Culturally and historically, the name can also be used for most of North Wales (for instance, the area covered by the Gwynedd Constabulary), corresponding to the approximate territory of the Kingdom of Gwynedd at its greatest extent.
