World leaders including Australian Prime Minister Scott Morrison, French President Emmanuel Macron, German Chancellor Angela Merkel and Canadian Prime Minister Justin Trudeau were also in attendance, seated close by the Queen.
Her Majesty looked in high spirits as she shared jokes with veterans and chatted with President Trump on the final day of his state visit to Britain, though at one point HM looked less than amused with the conversation.
Mr Trump and the First Lady touched down in London on Monday morning and headed straight for Buckingham Palace, where they were greeted by the Queen, the Prince of Wales and Camilla, Duchess of Cornwall.
The Trumps enjoyed afternoon tea at Clarence House ahead of a state banquet at the Palace, which was attended by 16 royals including Prince William and Kate, Duchess of Cambridge, Prince Andrew, Prince Edward and Sophie, Countess of Wessex, Anne, Princess Royal, the Duke and Duchess of Gloucester and Prince and Princess Michael of Kent.
Mr Trumps four adult children, Ivanka, Tiffany, Eric and Donald Jr along with PM Theresa May were also in attendance.
Prince Harry and Meghan Markle who is still on maternity leave after welcoming royal baby Archie Harrison, stayed at home in Frogmore Cottage in Windsor.
