William, Prince of Wales (William Arthur Philip Louis; born 21 June 1982), is the heir apparent to the British throne. He is the elder son of King Charles III and Diana, Princess of Wales.

William was born during the reign of his paternal grandmother, Queen Elizabeth II. He was educated at Wetherby School, Ludgrove School, and Eton College. He earned a Master of Arts degree in geography at the University of St Andrews, where he met his future wife, Catherine Middleton. They have three children: George, Charlotte, and Louis.

After university, William trained at the Royal Military Academy Sandhurst before serving with the Blues and Royals. In 2008, he graduated from the Royal Air Force College Cranwell and joined the RAF Search and Rescue Force in early 2009. From July 2015, he served for two years as a full‑time pilot with the East Anglian Air Ambulance.

William performs official duties and engagements on behalf of the monarch. He is patron of multiple charitable and military organisations, including the Tusk Trust, Centrepoint, The Passage, Wales Air Ambulance, and London's Air Ambulance Charity. Through the Royal Foundation, his work focuses on mental health, conservation, homelessness, and emergency workers. In 2020, he launched the Earthshot Prize, an initiative to incentivise environmental solutions.

William was made Duke of Cambridge immediately before his wedding in April 2011. He became Duke of Cornwall and Duke of Rothesay upon his father's accession to the throne on 8 September 2022. The following day, he was made Prince of Wales.
