Rosemary Rees MBE was a British aviator who worked for the Air Transport Auxiliary. She was second in command to Margot Gore at Hamble from the 29th September 1941 when the site became an all-women ATA ferry pool.

The Air Transport Auxiliary (ATA) was a British civilian organisation set up at the start of the Second World War with headquarters at White Waltham Airfield in Berkshire. The ATA ferried new, repaired and damaged military aircraft between factories, assembly plants, transatlantic delivery points, maintenance units (MUs), scrapyards, and active service squadrons and airfields, but not to naval aircraft carriers. It also flew service personnel on urgent duty from one place to another and performed some air ambulance work. Notably, around 10% of its pilots were women, and from 1943 they received equal pay to their male colleagues, a first for the British government.
