For supercentenarians known for anything other than their extreme age, see centenarian.

A supercentenarian (sometimes hyphenated as super-centenarian) is someone who has reached the age of 110 years or more, something achieved by only one in a thousand centenarians (based on European data). In turn, only about one supercentenarian in 44 lives to turn 115 (2% of 110-year-olds can expect to survive five more years).

The term has been around at least since the 1970s (as one citation, Norris McWhirter, editor of the Guinness Book of World Records, used the word in correspondence with age claims researcher A. Ross Eckler, Jr. in 1976), and was further popularized in 1991 by William Strauss and Neil Howe, in their book entitled Generations. Early references tend to mean simply "someone well over 100" but the 110-and-over cutoff is the accepted criterion of demographers.

While claims of extreme age have persisted from the earliest times in history, the earliest supercentenarian accepted by Guinness World Records is Thomas Peters, who was born in Groningen, Netherlands, April 6, 1745, and died there March 26, 1857 at almost 112 years of age (Guinness once accepted Pierre Joubert, but later dropped him, when it was discovered that he had been confused with his father). However, scholars such as Jean-Marie Robine consider Geert Adriaans Boomgaard of the Netherlands as well (1788-1899) to be the first verifiable case, as the alleged evidence for Peters has been 'lost'. The earliest supercentenarian to reach the age of 113 is Delina Filkins, who was born on May 4, 1815 and died on December 4, 1928 in Herkimer County, New York, USA.

Over eight hundred supercentenarians have been documented in history, and this is doubtless a fraction of the number who have really lived, but the majority of claims to this age do not have sufficient documentary support to be validated. This is slowly changing as those born after birth registration was standardized in more countries and parts of countries attain supercentenarian age.

The longest lifespan, documented beyond reasonable doubt, is the 122 years 164 days of Jeanne Calment (1875–1997).

The Guinness Book of World Records accepted in 1978 the claim that Shigechiyo Izumi was born June 29, 1865, and from the 1980 edition considered him the oldest person. He died February 21, 1986 (the 111th birthday of Jeanne Calment). However, subsequent research by some Japanese scholars has cast doubt on his claim, as his birth certificate is believed to refer to that of his older brother who died young and whose name might have been reused as a necronym.
