James Trevor 'Jamie' Oliver, MBE (born 27 May 1975), frequently nicknamed The Naked Chef, is an English chef and media personality, well known for his role in campaigning against the use of processed foods in national schools.

Oliver was brought up in Clavering, Essex, England, where his parents ran a pub, "The Cricketers", and used to practice in the kitchen. He was educated at Newport Free Grammar School. A dyslexic, he left school at 16 without any qualifications to attend Westminster Catering College. His first job was as a pastry chef at Antonio Carluccio's Neal Yard restaurant, where he first gained experience of Italian cuisine. Oliver then moved to The River Café, Fulham, as a sous chef, where he was noticed by the BBC.

On 24 June 2000, Oliver married former model Juliette Norton, also known as "Jools". The couple met in 1993 and have three daughters: Poppy Honey (born in March 2002), Daisy Boo (born 11 April 2003), and Petal Blossom Rainbow (born 3 April 2009). Oliver announced Petal's birth via Twitter. They live in Clavering, Essex.
