This is a list of the 29 longest spacewalks, also known as an extravehicular activity or EVA. "Agency" here refers to the organization under whose auspices the EVA was conducted (so a Swiss or Japanese astronaut would be listed under NASA if they wore NASA suits and were controlled by Mission Control Houston).

For details, see lists of spacewalks from 1965-1999, 2000-2014, and 2015-present.

List of spacewalks and moonwalks 1965-1999

This list contains all spacewalks and moonwalks performed from 1965 to 1999 where an astronaut has fully or partially left a spacecraft. Entries for moonwalks are shown with a gray background while entries for all other EVAs are uncolored.

List of spacewalks 2000-2014

This list contains all spacewalks performed between May 12, 2000, and October 22, 2014, where an astronaut fully or partially left a spacecraft. Since 1981, NASA has measured spacewalk duration from when the suits went to internal power until the start of airlock re-pressurization.
