Dobbins Air Reserve Base or Dobbins ARB (IATA: MGE, ICAO: KMGE, FAA LID: MGE) is a United States Air Force reserve air base located in Marietta, Georgia, a suburb about 20 miles (32 km) northwest of Atlanta. Originally known as Dobbins Air Force Base, it was named in honor of Captain Charles M. Dobbins, a World War II C-47 pilot who died near Sicily.

The installation is the home station of the host wing, the 94th Airlift Wing (94 AW) of the Air Force Reserve Command (AFRC) and its fleet of Hercules C-130 aircraft, and is also the location of the headquarters for AFRC's Twenty-Second Air Force (22 AF). It is also home to the Army Aviation Service Facility #2 (AASF#2) of the Georgia Army National Guard and their fleet of UH-60 Blackhawks. Dobbins is also home to Marine and Navy Reserve units.

Dobbins ARB has two runways which it shares with the General Lucius D. Clay National Guard Center (formerly Naval Air Station Atlanta) to its south. Runway 11/29 is the primary runway and is 10,000 feet (3,000 m) long and 300 feet (91 m) wide with directions 110 and 290 magnetic. The second runway, called an "assault strip", is a 3500×60-foot (1067×18-meter) runway referred to as 110-290, which is parallel to Runway 11/29.

Over 14,000 flight operations occur annually making the Dobbins complex an extremely active facility with diverse air traffic operations from all branches of the military and other US government agencies. This air traffic environment takes place within the area of the busiest airport in the world (Atlanta Hartsfield Airport) and is as busy as many medium-sized commercial airports.
