List of long course swimming pools in the United Kingdom

This is an annotated list of swimming pools in the United Kingdom which conform to the Olympic standard. Additionally, it lists other long-course facilities that do not quite come up to the full standard of 50 × 25 metres, 10 (middle 8 used) lanes.

At the start of the 21st century, the provision of 50-metre swimming pools in the United Kingdom was very poor for a developed country. Few universities possessed 50-metre pools, and there was a marked reluctance on the part of municipal authorities to build new public long-course facilities. However, the successful bid to hold the 2012 Summer Olympics in London added impetus to the development of new pools. A number of new venues were completed before and after the Games, although some existing pools were demolished and not replaced by 50-metre facilities.

, no university in the UK possesses an Olympic standard pool, though several have an 8-lane 50-metre pool. The Aberdeen Aquatics Centre, being part funded by the University of Aberdeen, is the main pool facility for the university.
