Grund Field (ICAO: NY55) is a small, privately owned general aviation airfield located in or near Ithaca, New York, in the Finger Lakes region of the United States. It serves private pilots and small aircraft operations rather than commercial airline traffic. The airfield is one of several small private landing strips in the greater Ithaca area, complementing the larger Ithaca Tompkins Regional Airport (ITH) which handles scheduled commercial service. Detailed operational and infrastructure information about Grund Field is limited due to its private nature.
