The Junior World Records in Swimming are the fastest times ever swum by a "junior" swimmer, with junior defined as the following ages (age as of December 31 of the year of the swim):
These records are kept/maintained by the FINA (now World Aquatics), and were initially established in March 2014 and based on the meet records from the Junior Worlds meet. [1]
Note: in some cases, there were existing world records (e.g. Katie Ledecky's 400, 800 and 1500 m freestyle, Rūta Meilutytė's 100 m breaststroke) that were not considered for these records (but were faster). Likewise more historical times by juniors were also not considered (e.g. Mary T. Meagher's 2:05.96 in the 200 m butterfly).
Long Course records can be established by breaking the initial time at a meet after April 1, 2014. [2] FINA World Junior Records in 25m pool are recognised starting on January 1, 2015.
Records are recognized for long course (50 m pool) and short course (25 m pool) in the following events:
Also recognized are mixed relay records for 4 × 100 medley and free relays.
All records were swum in finals unless noted otherwise.
