List of standardised Welsh place-names in Gwynedd

The list is based on recommendations provided by the Place-names Standardisation Panel, convened by the Commissioner, for expert advice on the standardisation of Welsh place-names.

The panel bases their decisions on a set of guidelines (currently dating to June 2023), specific to Welsh settlement names (such as those of villages, towns, and cities) and topographic features (such as lakes, mountains and rivers).

The panel does not cover house or building names, although similar principles could be applied to them or to names for new developments (for which the Commissioner offers their own advice to local authorities and housing developers).

[5][6] The Welsh name change of Barmouth, from Abermaw / Y Bermo to Abermo was criticised by a local historian in 2018,[7] in the November 2023 list, it seems to have been replaced with Y Bermo in Welsh.
