Buckingham Palace said in a statement that the monarch, 95, had accepted the Foreign Secretary's advice to delay the event.
It is understood the postponement is because of the situation in Ukraine and is unrelated to the Queen's health.
Her Majesty tested positive for COVID-19 on 20 February and had been isolating at her Berkshire abode.
According to The Daily Mail, the Queen enjoyed a family reunion with some of her grandchildren and great-grandchildren on Sunday, following her isolation period. She reportedly saw the Duke and Duchess of Cambridge, and their three children, along with Princess Beatrice and her baby daughter, Sienna.
