Louis de Cazenave (October 16, 1897 – January 20, 2008)[1] was, at the time of his death, the oldest surviving French veteran of World War I.

Two further French veterans, 108-year-old Fernand Goux and 109-year-old Pierre Picault who were the oldest living Frenchmen after Ponticelli's death as well as the last living Frenchmen born before 1900, died later in November 2008, but neither was officially recognized as the last French veteran of the war by the government of France because they served fewer than three months.

Louis de Cazenave was born and raised in Saint-Georges-d'Aurac in the Auvergne region of south central France.

[1] He found himself in various units before being assigned to the colonial infantry front in the 5th Senegalese Tirailleur Battalion and fought in the Battle of Chemin des Dames.

[1] During the Nazi occupation of France, he subscribed to the banned left-wing libertarian journal La Patrie Humaine and was imprisoned by the pro-Nazi Vichy regime.
