Bedlinog (Welsh: Bedd Llwynog) is a relatively isolated village built on a very steep hill in south Wales, United Kingdom, south east of Merthyr Tydfil.

It has a population of fewer than 2,000 people. The combined population of Bedlinog and Trelewis has been recently recorded as approximately 3,140. Previously, it was surrounded by coal mines and nearly all jobs were related directly to this trade but all the mines are now closed. Unemployment is high but the increasing prosperity and growth of Cardiff, only half an hour south by car, has created many commuter jobs and a feeling of optimism for the future.

In reality the view of the village as being isolated shows the parochial nature of the South Wales Valleys, as it is in fact only a 30 minute drive from Cardiff, 45 minutes from Swansea and 45 minutes from Newport - at the very most 5 minutes further away than the surrounding towns. The village is surrounded by rolling, green hills and from the top the Severn Estuary and the coast of Devon can be clearly seen.

It is known colloquially as 'Bedrock', after the town in The Flintstones.

During times past Bedlinog also was once nicknamed "Little Moscow" owing to the relatively high concentration of trade unionists with communist sympathies.
