The Mach Loop (also known as the Machynlleth Loop) is a series of valleys in the United Kingdom in west-central Wales, notable for their use as low-level training areas for fast aircraft. The system of valleys lies 13 km (8 mi) east of Barmouth between the towns of Dolgellau to the north and Machynlleth to the south, from the latter of which it takes its name. The training area is part of the United Kingdom Low Flying System and lies within Low Flying Area 7 (LFA7), which covers most of Wales.

Aircraft seen in the area include Royal Air Force Airbus A400M, Typhoon, Hawk jets and C-130J Super Hercules and Short Tucano as well as U.S. Air Force F-15C Eagles and F-15E Strike Eagles which are based at RAF Lakenheath and MC-130 and V-22 Osprey from RAF Mildenhall. Aircraft from other European nations have been sighted training in the Mach Loop, such as F-16 Fighting Falcons of the Belgian Air Component.
