The Nordic Junior Athletics Championships (Norwegian: Nordisk juniormesterskap i friidrett) is an annual outdoor track and field competition for athletes under-20 from the Nordic countries – Sweden, Norway, Finland, Denmark, and Iceland.

Finland and Sweden have chosen to set a lower age limit of 18, except for athletes competing in relay races only.

Norway, Denmark and Iceland have chosen not to have a lower age limit.

For much of its early history, it was a competition between Finland, Sweden and Norway only, with that being the arrangement until 1983, with exceptions of the 1962, 1964, and 1979 championships.

The competition broadened to include all Nordic states from 1983 onwards, with the exception of the period from 1989-93.
