John Condon (5 October 1897 – 24 May 1915) was an Irish soldier born in Waterford.

He was mistakenly believed to have been the youngest Allied soldier killed during the First World War, at the age of 14 years; he lied about his age and he claimed to be 18 years old when he signed up to join the army in 1913.

He was killed in action in a gas attack during the Second Battle of Ypres in 1915 and his body was not recovered for another ten years; his family were unaware that Condon was in Belgium until they were contacted by the British Army and told that he was missing in action.

At the present time, the headstone in Poelkapelle Cemetery and the CWGC record continue to assert the challenged data.

[1][2][3][4] Condon is the subject of the song of the same name by Mary Dillon, released in 2013 as a single from her debut album North.
