BBC National DAB is a digital audio broadcasting multiplex in the UK, for a number of radio stations which have UK wide coverage. The multiplex is owned and operated by the BBC and is transmitted from a number of transmitter sites across the country; it only carries BBC radio stations.

The following channels are receivable on any digital-equipped DAB radio in the BBC National DAB coverage area:

The BBC National DAB multiplex makes extensive use of dynamic ensemble reconfiguration to allow a number of part time services to broadcast. While these additional services are on air the bit rates of (one or more of) BBC Radio 3, BBC Radio 4, BBC Radio 5 Live, and data services are reduced.

The BBC planned to increase their coverage of their DAB multiplex to at least 92% of the population by adding 61 new transmitters to their existing coverage. BBC Asian Network was due to be axed in around 2011 after plans to close down the station were published and it also contained plans to close 6 Music. Since then 6 Music has been saved from closure after listening figures increased and a campaign was set up on Facebook which had 180,000 supporters.
