2018 AFL Women's Under-18 Championships
The 2018 NAB AFL Women's Under-18 Championships was played between May and July 2018, with six teams competing in the main 'Series 2' round robin tournament and with a further four playing in a two-match on-on-one exhibition as the competition's initial 'Series 1'.

Format
The competition was opened with 'Series 1', a set of closed competitions between four pairs of teams representing the country's eight largest states and territories. In 'Series 2' teams representing Vic Country, Vic Metro, Queensland and Western Australia were joined by Central and Eastern Allies teams representing teams of the combined regions of Northern Territory and South Australia (Central) as well as New South Wales, ACT and Tasmania (Eastern). Each team played a total of three matches in that series.

Vic Country finished the round-robin 'Series 2' as the only team undefeated in that series, making them the de facto tournament winners. The competition's best player award was jointly won by Vic Country's Nina Morrison and by the previous year's outright winner, Madison Prespakis of Vic Metro.
