Jeanne Louise Calment was a French supercentenarian and, with a documented lifespan of 122 years and 164 days, is the world's oldest verified person. Her longevity attracted media attention and medical studies of her health and lifestyle. She is the only person verified to have reached the age of 120.

A supercentenarian, sometimes hyphenated as super-centenarian, is a person who is 110 years or older. This age is achieved by about one in 1,000 centenarians. Supercentenarians typically live a life free of significant age-related diseases until shortly before the maximum human lifespan is reached.
