RCAF Station Grostenquin, also known as 2 (Fighter) Wing or 2 Wing, was a Royal Canadian Air Force (RCAF) station located five km north of the town of Grostenquin in the Moselle department, Lorraine, northeastern France. It was one of four RCAF wings, consisting of three fighter squadrons each, established in Europe in the early 1950s at the beginning of the Cold War. The other three wings were located at RCAF Station Marville (1 Wing) in France, and RCAF Station Zweibrücken (3 Wing) and RCAF Station Baden-Soellingen (4 Wing) in the former West Germany.
