The 2026 Oceania U20 Athletics Championships, also known colloquially by its former official title, the Oceania Junior Championships, will be an international athletics competition for Oceania athletes qualifying as juniors (born no earlier than 1 January 2007). The event is due to be staged in Darwin, Northern Territory, Australia from 21 to 23 May 2026. This will also be the sixth time Australia will host the Championships.
For the first time in its history, this edition of the U20 Championships will be exclusively for Pacific Island member federations. Hence, Australia and New Zealand will not be competing. The Championships will also be held concurrently with the Senior, U18, Para, Age Group (formerly Masters), and the U16 Championships.
The first draft schedule was published in December 2025.
