Gwyddelwern is a small village and community of 508 residents, situated approximately 2 miles (3.2 km) north of Corwen in Denbighshire in Wales. Historically the village was part of the Edeirnion district of Meirionnydd. Edeirnion was part of the Glyndŵr district of Clwyd from 1974 to 1996, when the area became part of the principal area of Denbighshire. The village straddles the A494 road (trunk road).

The name is often "poetically", but incorrectly, translated as The Irishman's Alder Grove. Gwyddel being Irishman, wern usually referring to a damp or swampy area arising from run-off from surrounding hills. However, the name is derived from gwyddeli, meaning thickets, hence the correct translation would be alder marsh in the thickets. In colloquial speech the village is often referred to simply as Gwyddel.

The outlook to the west of the village is dominated by the hills Mynydd-Rhŷd-Ddu and Bryn Gwenallt. To the south the view extends over the Dee Valley to the Berwyn Mountains and Arenig Fawr near Bala.

Colin Steele McRae, MBE (5 August 1968 – 15 September 2007) was a Scottish rally driver born in Lanark.

The son of five-time British Rally Champion Jimmy McRae and brother of rally driver Alister McRae, Colin McRae was the 1991 and 1992 British Rally Champion and, in 1995, became the first British person and the youngest to win the World Rally Championship Drivers' title. He still holds that record.

McRae's outstanding performance on the Subaru World Rally Team enabled the team to win the World Rally Championship Constructors' title three times in succession in 1995, 1996 and 1997. After a four-year spell with the Ford Motor Co. team, which saw McRae win nine events, he moved to Citroën World Rally Team in 2003 where, despite not winning an event, he helped them win the first of their three consecutive manufacturers' titles. He was appointed a Member of the Order of the British Empire for services to motorsport in 1996.

McRae died in 2007 when the helicopter he was piloting crashed near his home. The accident also claimed the lives of his son and two family friends. In November 2008 he was posthumously inducted into the Scottish Sports Hall of Fame.
