Groeslon (Welsh pronunciation^ⓘ; sometimes Welsh: Y Groeslon, 'the crossroads') is a small village in the community of Llandwrog in Gwynedd, Wales. The population was 880 at the 2011 census.

Nearby villages are Pen-y-groes, Carmel and Dinas. The village lies approximately five miles (8 km) south of Caernarfon.

Groeslon was by-passed in 2002 by the A487 road, a trunk road which cost around £12 million to complete. A bat bridge was constructed in 2010 to guide lesser horseshoe bats across the road.

Formerly an agricultural and slate mining village, Groeslon is now expanding as a commuter village for the surrounding towns, especially Caernarfon and Bangor. Its initial growth came as a result of the construction of the LMS railway in 1867. Groeslon railway station closed in December 1964. The railway line is now part of the national cycle route.

In the village there is one pub, the Tafarn Pennionyn.

At the bottom of the village, bordering the A487, a huge wall is visible. This is the wall to the Glynllifon estate, formerly the seat of Lord Newborough, which is now a country park and a campus of Coleg Meirion-Dwyfor specialising in land-based courses including agriculture, animal studies and veterinary nursing.

Groeslon is covered by a neighbourhood policing team based in Pen-y-groes.

Governance

Y Groeslon electoral ward is currently represented in Cyngor Gwynedd by Plaid Cymru councillor Llio Elenid Owen. This ward extends beyond the confines of Groeslon village, and the total population taken at the 2011 Census was 1,695. Historically, Groeslon was part of Caernarfonshire until the creation of Gwynedd in 1974.

The village forms part Llandwrog Community Council, currently chaired by councillor Gwyn Owen Jones.
