What are the World Junior Swimming Championships?
The World Aquatics Junior Swimming Championships are the world championships of junior swimming — the global title event for swimmers aged 14 to 18, raced on the full Olympic-program event schedule in a 50 m pool.[1] [2]
Who organizes them?
World Aquatics owns and organizes the championships; world junior records are ratified by the federation, and results seed the sport's global junior rankings.[1]
When and where are they held?
Every two years, in odd-numbered years, in a rotating host city — most recently Otopeni, Romania, 19–24 August 2025.[1] [3]

| 2011 | 50 m | Lima (PER) |
| 2008 | 50 m | Monterrey (MEX) |
| 2006 | 50 m | Rio de Janeiro (BRA) — inaugural edition |
Eligibility: swimmers aged 14–18 on 31 December of the competition year (unified in 2023; previously girls 14–17, boys 15–18).[2]
Since when do they exist?
The first edition was held in Rio de Janeiro in 2006, and the championships have since become the recognized summit of junior swimming worldwide.[2]
How do swimmers qualify?
Entry runs through the national federations: swimmers must meet World Aquatics' published qualifying standards within the eligibility ages and are selected and entered by their federation as national junior team members — many countries pick their teams at junior nationals or trials.[4]
Why do they matter?
A World Junior medal is the highest age-group honor in swimming, and the championships are the sport's proving ground: recent editions have produced world junior records and launched swimmers directly onto Olympic and senior world podiums. Selection alone marks an athlete as among the best juniors in their country.[2] [3]
Who competes?
National junior teams from across World Aquatics' member federations — several hundred of the world's best 14-to-18-year-old swimmers per edition.[1] [3]
