Her Majesty arrived at the Royal Albert Hall alongside senior royals for the concert to honour the UK’s war dead.
Wearing a black dress and a remembrance poppy brooch, the Queen, 92, looked solemn as she took her seat in the royal box ahead of performances by Tom Jones and Sheridan Smith.
Prince Philip, who retired from his royal duties last year, is not in attendance.
Her Majesty was joined in the royal box by Prince Charles and the Duke and Duchess of Cambridge.
Tonight’s event is organised by the Royal British Legion as part of London’s annual festival of remembrance.
The concert serves as a thank you to those who gave their lives in service for Britain and the Commonwealth.
This year’s event, on the eve of Armistice Day, takes on a special significance as it marks 100 years since the end of World War 1.
A host of other royals attended, including the Duke and Duchess of Sussex are also in attendance after Prince Harry travelled into central London from his remembrance duties at Twickenham earlier today.
The Festival of Remembrance began in 1927 as a way to honour those who had fought and died in WW1.
But over the years it has evolved to pay tribute those killed in past and more recent conflicts.
Tonight’s concert, which is hosted by the BBC’s Huw Edwards, will feature performances from Sir Bryn Terfel as well as Tom Fletcher and Danny Jones from McFly.
The evening will also see British cellist Sheku Kanneh-Mason take to the stage alongside the Kingdom Choir. Both acts played at the Duke and Duchess of Sussex’s wedding earlier this year.
The concert will be broadcast on BBC One at 8.30pm.
