Fred Parkinson Holliday, DSO, MC, AFC (20 February 1888 – 5 March 1960), was an Australian-born Canadian fighter pilot and ace of the First World War. He shot down 17 German aircraft between his entry into the war and its end, making him the 11th highest-scoring Australian-born pilot of the war. He served with the RFC and RAF throughout, in the No. 48 Squadron. He was awarded the Military Cross on 26 July 1917 for a particularly successful encounter with five German aircraft, and was later given the Distinguished Service Order.
