List of last surviving veterans of World War I

The following is a list of known surviving veterans of the First World War (July 28, 1914–November 11, 1918). The total number of participating personnel is unknown, but there were an estimated nine million military casualties during the conflict.

Veterans, for this purpose, are defined as people who were members of the armed forces of one of the combatant nations up to and including the date of the Armistice. Other WWI-era veterans are listed separately. This policy may vary from the policy in actual use in some countries.

111-year-old British WWI veteran Henry Allingham, born June 6, 1896, is currently the oldest living verified veteran. Emiliano Mercado del Toro of Puerto Rico (August 21, 1891–January 24, 2007), who died aged 115, is the oldest authenticated veteran, from any conflict, to have ever lived.

Living in Canada&mdash;1 veteran
The Canadian House of Commons has approved a state funeral for the last World War I veteran to have served in the Canadian forces to die. This is to honour the 600,000 Canadians that fought in that war. See also John Babcock, who is listed under veterans living in the United States.

Living in France&mdash;3 veterans
The French government has approved a state funeral for the last official World War I French veteran to die.

Living in the UK&mdash;3 veterans
Her Majesty's Government approved on June 27, 2006 a National Memorial Service at Westminster Abbey to take place after the passing of the last known WWI veteran.

World War I-era veterans&mdash;5 veterans
Listed here are those that joined the armed services after the Armistice date but before the Treaty of Versailles, or where there is debate on their join-date, or whose military service is sometimes viewed as outside the scope of "WWI", but are considered WWI-era vets by the press or by their respective governments, or served in a related conflict.

Unverified WWI veteran claims&mdash;3 veterans
These are claims that were included in the press, but have not been verified by a government-sanctioned body or actual records located. To be a 'claim', there must be at least a citation. In the case of the two Americans, veteran status has been claimed by the men in question, but they are currently unsupported by physical evidence or independent research.
