Jon Brower Minnoch (September 29, 1941 – September 4, 1983) was an American man who is the heaviest recorded human in history, weighing approximately 1,400 lb (635 kilograms; 100 stone) at his peak. Obese since childhood, Minnoch normally weighed 800–900 lb (363–408 kilograms; 57–64 stone) during his adult years. He owned a taxi company and worked as a driver around his home in Bainbridge Island, Washington.

In an attempt to lose weight, Minnoch went on a 600 kcal (2,500 kJ) per day diet under a doctor's orders. As a result, Minnoch was bedridden for about three weeks before finally agreeing to go to a hospital in March 1978. It took over a dozen firefighters to transport him to the University of Washington Medical Center in Seattle. Doctors diagnosed Minnoch with a massive edema, and an endocrinologist estimated his weight to be approximately 1,400 lb (635 kilograms; 100 stone). His physicians placed him on a 1,200 kcal (5,000 kJ) per day diet where, after around two years in the hospital, he lost over 900 lb (408 kg; 64 st)—the largest documented human weight loss at the time. After leaving the hospital, Minnoch regained much of the weight and died in September 1983, weighing nearly 800 lb (363 kg; 57 st) at his death. Minnoch's casket took up two burial spots at Mount Pleasant Cemetery in Seattle.
