Kings Trough (sometimes spelled King's Trough) is an undersea trough in the North Atlantic Ocean. It is located on the east side of the Mid-Atlantic Ridge, northwest of the Açores-Biscay Rise and roughly 400 km (250 mi) north-northeast of the Azores. It is approximately 400 km (250 mi) long, running in a northwest–southeast direction. To the east it branches into the Peake Deep and Freen Deep. The center depth is 4,500 m (14,800 ft). Surrounding the trough are high ridges and seamounts, such as the Antialtair Seamount and the Crumb Seamount complex.[1] Various explanations for the complex have been suggested, ranging from compression,[2] a former plate boundary,[3] transform faulting or even an oblique meteor impact.[4]

The trough, being in an apparently geologically stable region, has been studied as a possible location for radioactive waste disposal.[5]
