List of oldest living state leaders

This article lists the 100 oldest living current or former state leaders whose age can be demonstrated beyond reasonable doubt. State leaders are defined to include heads of state (including representatives who act in their stead, generally a governor-general), heads of government and internationally recognized de facto leaders^[α] of sovereign states with significant international recognition. Leaders are not included if no reliable secondary sources have confirmed that the leader is alive within the last 10 years. The oldest living former state leader is Guillermo Rodríguez of Ecuador at the age of 100 years, 242 days. Leaders currently in office are in bold in green, with Paul Biya of Cameroon being the oldest currently serving head of state.^[2]
