Recordiau Anhrefn (Welsh for Anhrefn Records) was a record label established in 1983 by Rhys Mwyn.Based in the small mid-Wales village of Llanfair Caereinion, before Rhys and his brother Sion Sebon moved to Bangor, North Wales, the record label was initially an outlet for their own band Yr Anhrefn but soon went on to release records by other Welsh groups, providing early exposure for such influential names as Datblygu, Fflaps and Llwybr Llaethog.
