Prince Edward, Duke of Edinburgh (Edward Antony Richard Louis; born 10 March 1964), is a member of the British royal family. He is the youngest child of Queen Elizabeth II and Prince Philip, Duke of Edinburgh, and the youngest sibling of King Charles III. He was born third in the line of succession to the British throne and is now 15th.

Born at Buckingham Palace during the reign of his mother, Edward studied at Heatherdown School and completed his A-Levels at Gordonstoun before spending part of his gap year teaching at Whanganui Collegiate School in New Zealand. He then went up to read history at Jesus College, Cambridge, graduating in 1986 with a Bachelor of Arts degree from the University of Cambridge. After a brief stint in the Royal Marines, he worked as a theatre production assistant at the Really Useful Theatre Company before assisting in television production. He later formed his own company, Ardent Productions.

Edward stepped down from the company in 2002 to begin full-time duties as a working member of the royal family, and undertook engagements on behalf of his mother. He holds patronage with over 70 charities and organisations, including the National Youth Theatre, the Sport and Recreation Alliance and the British Paralympic Association. His charity work focuses on the arts, athletics, and the development of the Duke of Edinburgh's Award, which centres on fitness, wellbeing and community service.

Edward was given the title of Earl of Wessex prior to marrying Sophie Rhys-Jones in 1999. They have two children: Lady Louise Mountbatten-Windsor and James Mountbatten-Windsor, Earl of Wessex. Edward's mother conferred him the additional title of Earl of Forfar in 2019. On Edward's 59th birthday in 2023, his brother Charles III granted him the title Duke of Edinburgh as a life peerage, a dukedom previously held by their father, who died in 2021, then briefly by Charles.

Edward was born at 8:20 pm on 10 March 1964 at Buckingham Palace, London, as the third son and the fourth and youngest child of Queen Elizabeth II and Prince Philip, Duke of Edinburgh. He is the most recent child to be born to a reigning British monarch. His birth was the only one witnessed by his father. He was baptised on 2 May 1964 in the private chapel at Windsor Castle.

As with his three elder siblings, Charles, Anne, and Andrew, a governess was appointed to look after Edward and was responsible for his early education at Buckingham Palace before he attended Collingham College, Kensington (then known as Gibbs School). In September 1972, he joined Heatherdown School, near Ascot in Berkshire. Later, as his father and elder brothers had done before him, he moved to Gordonstoun in northern Scotland, where he was appointed head boy in his last term. Edward obtained a C-grade in English and two D-grades in history and politics at A-level, and after leaving school spent a gap year abroad, working as a house tutor and junior master for two terms at the Wanganui Collegiate School in New Zealand.

Upon his return to the United Kingdom, Edward studied at Jesus College, Cambridge, where he read history. His admission to the university despite poor A-Level results caused some comment. Edward graduated in 1986 with a Bachelor of Arts degree (Lower Second Hons).

After graduating in 1986, Edward joined the Royal Marines, who had reportedly sponsored his tuition at Cambridge on condition of future service. He had signed up to join the Royal Marines in September 1983. In January 1987, he dropped out of the commando course having completed one-third of the 12-month training. Media reported that Prince Philip, who was the Captain General Royal Marines, was displeased, but Prince Edward later said that his father had not put undue pressure on him to change his mind. Others stated that Philip was the most sympathetic family member toward his son's decision. Buckingham Palace said that Edward's decision came after "much consideration" and that he was leaving with great regret "but has concluded that he does not wish to make the service his long-term career".
