Peter Jeffrey DSO, DFC (6 July 1913 – before 10 April 1997) was a senior officer and fighter ace in the Royal Australian Air Force (RAAF). Born in Tenterfield, New South Wales, he joined the RAAF active reserve in 1934, and transferred to the Permanent Air Force (PAF) shortly before World War II. Posted to the Middle East in July 1940, Jeffrey saw action with No. 3 Squadron and took command of the unit the following year, earning the Distinguished Flying Cross for his energy and fighting skills. He was appointed wing leader of No. 234 Wing RAF in November 1941, and became an ace the same month with his fifth solo victory. The next month he was awarded the Distinguished Service Order for his achievements, which included rescuing a fellow pilot who had crash landed in the desert.
