The Aquatics GB Swimming Championships are an annual event organised by Aquatics GB (the governing body of swimming in the United Kingdom).

The event is usually held in March or April each year in a long course (50 m) swimming pool, with the results usually acting as selection trials for upcoming international level competitions due to be held in the following summer season.
