List of longest-living state leaders

This article lists the 100 oldest heads of state or heads of government of sovereign states (often a President or a Prime minister), since 1800. This list includes those who are leaders over a sovereign and internationally recognized state. States with limited recognition are not included (exceptions being for states considered independent in their own right, including members of the Warsaw Pact). A leader who doesn't have any reliable source about their death currently or has been alive with a source for more than 10 years old are not included in the list. The longest-lived verifiable state leader is Chau Sen Cocsal Chhum of Cambodia at the age of 103 years, 143 days. Muhammad al-Muqri of Morocco is the only state leader who possibly could've lived longer, at the age of either 103 years, 219 days or 97 years, 219 days. Leaders who are currently living are in bold in green, with Guillermo Rodríguez of Ecuador being the longest-living at the age of 102 years, 134 days.
