The 127th (Parachute) Field Ambulance was a Royal Army Medical Corps unit of the British airborne forces during the Second World War.

A field ambulance (FA) is the name used by the British Army and the armies of other Commonwealth nations to describe a mobile medical unit that treats wounded soldiers very close to the combat zone. In the British military medical system that developed during the First World War, the FAs formed an intermediate level in the casualty evacuation chain that stretched from the regimental aid posts near the front line and the casualty clearing stations located outside the range of the enemy's artillery. FAs were often assigned to the brigades of a division.
