Blenheim Palace Festival, the spectacular open-air concert series set against the breathtaking backdrop of one of Britain’s most iconic palaces, has revealed Mariah Carey, one of music’s most celebrated voices, as the fifth headliner for 2027.

The elusive chanteuse and best-selling female artist of all time, with over 200 million records sold globally, will bring her Firefly summer tour to the UNESCO World Heritage Site on Thursday 1 July 2027. She will be supported by hit R&B group Eternal.

Bringing the summer heat to the baroque grandeur of Blenheim Palace, Marah Carey has amassed over 19 Billboard Hot 100 Number 1 Singles to date – more than any solo artist in history. Her beloved 1994 yuletide hit All I Want For Christmas Is You has become one of the longest-charting singles of any genre, spending 65 weeks on Billboard’s Hot 100. Just this year, Carey was honoured with the VMAs coveted Video Vanguard Award and continued her award streak by being named MusiCares Person of the Year. In 2015, she was awarded a star on the Hollywood Walk of Fame, and in 2023, she became one of the first 13 recipients of the BRIT Billion Award for surpassing one billion streams in the United Kingdom. 

Tickets for Mariah Carey at Blenheim Palace Festival 2027 go on general sale from 9am on Friday 13 November 2026 via blenheimpalacefestival.com
