.cymru is one of two geographic top level domains (GeoTLD) for Wales (the other being .wales).

The TLD was proposed by the British internet registry company Nominet, which has run the domain for the UK (.uk) since 1996.

[2] The proposal initially ran into conflict with .cym, proposed by the Wales-based, not-for-profit dotCYM organisation, which advocates for the Welsh language and culture.

On 30 September 2014, the Llywydd of the Senedd officially moved Senedd websites and other sites to new ".cymru" and ".wales" domains which are geographic top-level domains specific to Wales.

Wales Online, Daily Post, the Welsh Rugby Union, the Millennium Stadium, Golwg360, Bloc, Gwalia, Atlantic PLC, Orchard and Portmeirion were among others who also switched over to the domains.
