Stephen Robert Irwin (22 February 1962 – 4 September 2006) was an Australian zookeeper, conservationist, television personality, wildlife educator, and environmentalist. Nicknamed the "Crocodile Hunter", he is regarded as an influential figure in Australian popular culture, and as one of the greatest conservationists of all time.
Irwin grew up around crocodiles and other types of reptiles and was educated regarding them by his father, Bob. He achieved international fame in the late 1990s from the television series The Crocodile Hunter, an internationally broadcast wildlife documentary series that he co-hosted with his wife, Terri. The couple also hosted the series Croc Files, The Crocodile Hunter Diaries, and New Breed Vets. They also co-owned and operated Australia Zoo, founded by Steve's parents in Beerwah, Queensland. They had two children, Bindi and Robert.
On 4 September 2006, Irwin died from an injury caused by a stingray while filming an underwater documentary in the Great Barrier Reef. His death became international news and was met with expressions of shock and grief by fans, the media, governments, and non-profit organisations.
