The tallest mountain in the Eastern Hemisphere is Mount Everest, located in the Mahalangur Himal sub-range of the Himalayas.

While some people might argue for other mountains like Puncak Jaya (also known as Carstensz Pyramid) in Indonesia, Mount Everest is considered the tallest when measured from sea level, standing at 8,848.86 meters (29,031.7 feet).
