Lieutenant John Nicholas Sergiades was an English officer of the British Army who was killed during the First World War.

He was born on 7 March 1887,[1] in Toxteth Park, Liverpool, the son of corn merchant Nicholas, born in the Ottoman Empire to Greek parents, and Eliza Olive Sergiades (née Lucy), local to the area. Sergiades received his education at Marlborough College[1] before entering his father's trade.

Sergiades died on 30 July 1916, during the Somme Offensive, while serving with the 19th (Service) Battalion (3rd City), The King's (Liverpool Regiment), one of four battalions collectively known as the 'Liverpool Pals'. He died during an abortive effort to capture the village of Guillemont, in which three of the Pals' battalions sustained more than 1,000 casualties. Sergiades was one of 192 officers and other ranks from the 19th who perished in the attack.

He has no known grave and is commemorated by the Thiepval Memorial.
