Richard Stone (born 5 June 1951) is a British painter, specialising in portraits. In 1973, at the age of 22, he became the youngest commissioned royal portrait painter in almost 200 years.^{[1][better source needed]} Stone claims to have secured the commission by cold-calling Clarence House and saying "I could be a latter-day Rembrandt".^[2] He has completed commissioned portraits of Queen Elizabeth II, the Queen Mother, Princess Margaret, Princes Philip and Andrew, and King Charles III.^[2] He also painted the official Downing Street portrait of Margaret Thatcher, who upon inspecting his work, requested that he add her handbag to the portrait.^[3] His portraits hang at Buckingham Palace, the National Portrait Gallery (London), and the National Portrait Gallery (Australia).^[1]

Stone's 1992 portrait of Queen Elizabeth II was used by the BBC during the announcement of her death and in the subsequent obituary broadcasts.^[4]
