List of Mount Everest expeditions
This is a list of expeditions to Mount Everest. Many of these are mountaineering expeditions for exploration, sport, science or fundraising.

Introduction
There have been many expeditions throughout the 20th (1900s) and 21st (2000s) centuries, and the amount increased in the late 20th century.
The first expedition was a reconnaissance expedition in 1921, and after a few decades an expedition in 1953 reached the top of Everest. Everest expeditions, especially in the late 1900s had a certain grandiose reputation, because they were often such large undertakings. The 1953 expedition had 320 porters that carried supplies across a remote wilderness. The 1963 American expedition had over 900 porters that carried over 25 tons of supplies, supporting a climbing crew of dozens.
