Coincy Aerodrome was a temporary World War I airfield in France.
In its short history it was used by French, German, and American squadrons (at different times).
The airfield was established by the French "Aéronautique Militaire" in early 1918 and used by its escadrilles until it had to be evacuated in May 1918 before the German push towards Paris.
It was then used by the German Jastas until the Allied counter-offensive liberated the area in the first days of August 1918.
