The figures show that more than 35 million people tuned in to BBC Radio per week during the measurement period (January 3 to March 27) – the biggest total since new research methodology was introduced in January 1999.
The total was boosted by record performances from Radio 1 and Radio 4, and digital-only networks Radio 6 Music, Radio 1Xtra and Radio 7 (now Radio 4 Extra).
RAJAR statistics also show that 47.3 million people tuned into their favourite radio stations every week – 91.6% of the country's population aged 15+.
Tim Davie, Director BBC Audio & Music, said: "It is quite brilliant to see radio reaching a record number of listeners in the digital age. These results speak to the unique quality of radio in the UK and reflect our work as an industry to keep innovating to attract new listeners. From a BBC perspective, the record results reflect the unique strength of our programme makers and the growing value of distinctive radio stations."
