<P> The Mariana Trench or Marianas Trench , located in the western Pacific Ocean approximately 200 kilometres ( 124 mi ) east of the Mariana Islands , is the deepest point in the world 's oceans . It is a crescent - shaped trough in the Earth 's crust averaging about 2,550 km ( 1,580 mi ) long and 69 km ( 43 mi ) wide . The maximum - known depth is 10,994 metres ( 36,070 ft ) ( ± 40 metres ( 130 ft ) ) at the southern end of a small slot - shaped valley in its floor known as the Challenger Deep . However , some , unrepeated , measurements place the deepest portion at 11,034 metres ( 36,201 ft ) . For comparison : if Mount Everest were dropped into the trench at this point , its peak would still be over 2 kilometres ( 1.2 mi ) underwater . </P>
