The 7.5 cm Feldkanone 16 neuer Art (7.5 cm FK 16 nA) was a field gun used by Germany in World War II. Originally built as the World War I-era 7.7 cm FK 16, surviving guns in German service were re-barrelled during the early 1930s in the new standard 7.5 cm calibre. It was not modernized for motor towing and retained its original wooden spoked wheels and two crew seats on the face of the gun shield.
