For the swimming competitions at the 2012 Summer Olympics the following qualification systems were in place. The list has been updated to 20 August 2011. Qualification ended on 3 July 2012.

Qualifying standards

A National Olympic Committee (NOC) may enter up to 2 qualified athletes in each individual event if both meet the Olympic Qualifying Time (OQT). 1 athlete per event can potentially qualify should they meet the Olympic Selection Time (OST) and if the quota of 900 athletes has not been met. NOCs may enter swimmers regardless of time (1 swimmer per sex) if they have no swimmers meeting either standard entry time.

The qualifying time standards must be obtained in Continental Championships, National Olympic Trials or International Competitions approved by FINA in the period 1 March 2011 to 3 July 2012.
