List of standardised Welsh place-names in Ceredigion

The list of standardised Welsh place-names, for places in Ceredigion, is a list compiled by the Welsh Language Commissioner to recommend the standardisation of the spelling of Welsh place-names, particularly in the Welsh language and when multiple forms are used, although some place-names in English were also recommended to be matched with the Welsh. The list contains 237 entries, as of November 2023.

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). The panel may also have used additional guidelines.

The list was first published in 2018, and took years to put together. Upon creation, these lists were published under the Open Government Licence 3.0.

In 2021, Ceredigion County Council announced it would consider implementing the list's recommendations. The addition of hyphens was described as "hyphengate".
