Ozzy Osbourne died on July 22, 2025, at the age of 76. The official cause of death was a heart attack (acute myocardial infarction) that occurred out of hospital, compounded by coronary artery disease and Parkinson's disease with autonomic dysfunction. Paramedics reportedly worked for hours attempting to save him, and an air ambulance was dispatched to his home in Buckinghamshire, England, but he was ultimately not revived. He had been battling Parkinson's disease, which had significantly impacted his health in recent years, along with other heart-related issues. His death came just 17 days after his final performance with Black Sabbath during a farewell concert. In summary, Ozzy Osbourne's death was primarily caused by a heart attack influenced by underlying coronary artery disease and complications related to Parkinson's disease. He died peacefully surrounded by his family at home.
