Gordon James Ramsay (/ˈræmzi/ RAM-zee; born (1966-11-08)8 November 1966) is a British celebrity chef, restaurateur, television presenter, and writer. His restaurant group, Gordon Ramsay Restaurants, was founded in 1997 and has been awarded 17 Michelin stars overall and currently holds eight. His signature restaurant, Restaurant Gordon Ramsay in Chelsea, London, which he founded, has held three Michelin stars since 2001 and is currently run by chef Matt Abé. After rising to fame on the British television miniseries Boiling Point in 1999, Ramsay became one of the best-known and most influential chefs in the world.

Ramsay's media persona is defined by his fiery temper, aggressive behaviour, strict demeanour, and frequent use of profanity, while making blunt, critical, and controversial comments, including insults and sardonic wisecracks about contestants and their cooking abilities. He is known for presenting television programmes about competitive cookery and food, such as the British series Hell's Kitchen (2004), Ramsay's Kitchen Nightmares (2004–2009, 2014), and The F Word (2005–2010), with Kitchen Nightmares winning the 2005 British Academy Television Award for Best Feature, and the American versions of Hell's Kitchen (2005–present), Kitchen Nightmares (2007–present), MasterChef (2010–present), and MasterChef Junior (2013–present), as well as Hotel Hell (2012–2016), Gordon Behind Bars (2012), Gordon Ramsay's 24 Hours to Hell and Back (2018–2020), and Next Level Chef (2022–present).

Ramsay was appointed an OBE by Queen Elizabeth II in the 2006 New Year Honours list for services to the hospitality industry. He was named the top chef in the UK at the 2000 Catey Awards, and in July 2006 he won the Catey for Independent Restaurateur of the Year, becoming the third person to win three Catey Awards. Forbes listed his 2020 earnings at US $70 million and ranked him at No.19 on its list of the highest-earning celebrities.

Gordon James Ramsay was born in Johnstone, Scotland, on 8 November 1966, the son of Helen (née Cosgrove), a nurse, and Gordon James Sr., who worked as a swimming pool manager, welder, and shopkeeper. He has an older sister, a younger brother, and a younger sister. When he was nine years old, he moved with his family to England and grew up in the Bishopton area of Stratford-upon-Avon. He has described his early life as "hopelessly itinerant" and said his family moved constantly owing to the aspirations and failures of his father, who was an occasionally violent alcoholic; Ramsay described him as a "hard-drinking womaniser". In his autobiography, he revealed that his father abused and neglected the children and his mother. He worked as a pot washer in a local Indian restaurant where his sister was a waitress. He had hoped to become a footballer and was first chosen to play under-14 football at the age of 12, but his early footballing career was marked by injuries; after a serious knee injury, he was forced to give it up. At the age of 16, he moved out of the family home and into a flat in Banbury.

Ramsay's interest in cooking began in his teenage years; rather than be known as "the football player with the gammy knee", he decided to pay more serious attention to his culinary education at age 19. Ramsay enrolled at North Oxfordshire Technical College, sponsored by the Rotarians, to study hotel management. He described his decision to enter catering college as "a complete accident".

In the mid-1980s, Ramsay worked as a commis chef at the Wroxton House Hotel. He ran the kitchen and 60-seat dining room at the Wickham Arms until he quit after having sex with the owner's wife. Ramsay then moved to London, where he worked in a series of restaurants until being inspired to work for Marco Pierre White at Harveys.

After working at Harveys for two years and ten months, Ramsay, tired of "the rages and the bullying and violence", decided that the way to further advance his career was to study French cuisine. White discouraged Ramsay from taking a job in Paris, instead encouraging him to work for Albert Roux at Le Gavroche in Mayfair. Ramsay decided to take his advice, and there, Ramsay met Jean-Claude Breton, who later became his maître d'hôtel at Restaurant Gordon Ramsay. After Ramsay worked at Le Gavroche for a year, Roux invited him to work with him at Hotel Diva, a ski resort in the French Alps, as his number two. From there, a 23-year-old Ramsay moved to Paris to work with Guy Savoy and Joël Robuchon, both Michelin-starred chefs. He continued his training in France for three years, before giving in to the physical and mental stress of the kitchens and taking a year to work as a personal chef on the private yacht Idlewild, based in Bermuda. The role on the boat saw him travel to Sicily and Sardinia, Italy, and learn about Italian cuisine.

Upon his return to London in 1993, Ramsay was offered the position of head chef, under chef-patron Pierre Koffmann, at the three-Michelin-starred La Tante Claire in Chelsea. Shortly thereafter, Marco Pierre White reentered his life, offering to set him up with a head chef position and 10% share in the Rossmore, owned by White's business partners. The restaurant was renamed Aubergine and won its first Michelin star 14 months later. In 1997, Aubergine won its second Michelin star. A dispute with Ramsay's business owners, who wanted to turn Aubergine into a chain, and Ramsay's dream of running his own restaurant led to his leaving the partnership in July 1998. He has described the decision to set out on his own as "the most important day of my entire cooking career; the most important decision of my life."
