John "Barney" Hines (1873–1958) was a British-born Australian soldier of World War I, known for his prowess at collecting 'souvenirs' from German soldiers. Hines was the subject of a famous photo taken by Frank Hurley which depicted him surrounded by the loot he had captured during the Battle of Polygon Wood in September 1917. This image is among the best-known Australian photographs of the war.
