Eastern West Virginia Regional Airport (IATA: MRB, ICAO: KMRB, FAA LID: MRB), also known as Shepherd Field, is a civilian-owned, public use airport located four nautical miles (5 mi, 7 km) south of the central business district of Martinsburg, a city in Berkeley County, West Virginia, United States.

The 167 AW is an Air Mobility Command (AMC)-gained unit which began operating the Boeing C-17 Globemaster III aircraft in January 2015.

The last Lake Central timetable before merging with Allegheny in 1968 showed three flights a day, with one to Elkins, WV, and two to Baltimore, using Nord 262 prop jets.

Allegheny eventually upgraded the aircraft to Convair 580 prop jets and the nonstop service changed to Washington (DCA) and Clarksburg, WV, with three or four departures a day.

It has one runway designated 08/26 with a primarily asphalt surface with portions composed of portland cement concrete (PCC) measuring 8,815 by 150 feet (2,687 x 46 m).
