Irwin was born on his mother's birthday to Lyn and Bob Irwin in Essendon, a suburb of Melbourne, Victoria. He was of Irish descent on his father's side. He moved with his parents as a child to Queensland in 1970, where he attended Landsborough State School and Caloundra State High School. Irwin described his father as a wildlife expert interested in herpetology, while his mother Lyn was a wildlife rehabilitator.

On 4 September 2006, Irwin was on location at Batt Reef, near Port Douglas, Queensland, taking part in the production of the documentary series Ocean's Deadliest. During a lull in filming caused by inclement weather, Irwin decided to snorkel in shallow waters while being filmed in an effort to provide footage for his daughter's television programme.  While swimming in chest-deep water, Irwin approached a stingray with an approximate span of two metres (6.5 ft) from the rear, in order to film it swimming away.  According to the incident's only witness, "All of a sudden [the stingray] propped on its front and started stabbing wildly with its tail. Hundreds of strikes in a few seconds". Irwin initially believed he only had a punctured lung. However, the stingray's barb pierced his heart, causing him to bleed to death. The stingray's behaviour appeared to have been a defensive response to being boxed in. Crew members aboard Irwin's boat administered CPR and rushed him to the nearby Low Isles where medical staff pronounced him dead.  Irwin's death is believed to be the only fatality from a stingray ever captured on video.  Footage of the incident was viewed by Queensland state police as part of their mandatory investigations. All copies of the footage were then destroyed at the behest of Irwin's family. Production was completed on Ocean's Deadliest, which was broadcast in the US on the Discovery Channel on 21 January 2007. The documentary was completed with footage shot in the weeks following the accident, but without including any mention of Irwin's accidental death.
