Gwynedd (Welsh pronunciation: [ˈɡwɨ̞nɛð]) is an area in north-west Wales, named after the old Kingdom of Gwynedd. As a local government area it is the second biggest in terms of geographical area and 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 two local government areas of Gwynedd and the Isle of Anglesey. 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.

Gwynedd is the home of Bangor University and includes the scenic Llŷn Peninsula, and most of the Snowdonia National Park.

Gwynedd was an independent kingdom from the end of the Roman period until the 13th Century when it was conquered and subjugated by England. The modern Gwynedd was one of eight Welsh counties originally created on 1 April 1974 under the Local Government Act 1972, based on the principal territory of the former realm. It covered the entirety of the old counties of Anglesey, and Caernarfonshire along with all of Merionethshire apart from Edeirnion Rural District (which went to Clwyd), and also a few parishes in Denbighshire: Llanrwst, Llansanffraid Glan Conwy, Eglwysbach, Llanddoged, Llanrwst and Tir Ifan.

Peredur Wyn ap Gwynedd (born 1970) (age 41) is a Welsh guitarist. He was born and raised in South Wales and currently resides in London. His brother, Rheinallt ap Gwynedd, was the bassist for the band Apollo 440 and his sister, Llinor ap Gwynedd, is an actress.

Ap Gwynedd was a judge on Welsh talent show "Waw Ffactor" having been the guitarist with acts such as Natalie Imbruglia, Norman Cook, Sophie Ellis Bextor and Mylène Farmer. In 2006 he joined Pendulum, with whom he had recently worked with on their song 'Girl In The Fire'.

Ap Gwynedd performed on songs from Pendulum's In Silico and Immersion albums.

Whilst performing with Pendulum, ap Gwynnedd mainly uses Peavey guitars, primarily the HP Signature Series model. He has said in an interview that he uses Native Instruments Guitar Rig, software effects processor, to assist in emulating synthetic sounds when performing live shows.
