The 2018 Asian Women's U17 Volleyball Championship, also referred to as the 2018 SMM Est Cola Asian Girls' U17 Volleyball Championship for sponsorship reasons, was the twelfth edition of the Asian Youth Women Volleyball Championship, a biennial international volleyball tournament organised by the Asian Volleyball Confederation (AVC), that year with the Thailand Volleyball Association (TVA), for the under-17 women's national teams of Asia. The tournament was held in Nakhon Pathom, Thailand, from 20 to 27 May 2018.
A total of thirteen teams played in the tournament, with players born on or after 1 January 2001 eligible to participate.
The thirteen AVC member associations (including the India volleyball team under the Indian Olympic Association, who was suspended by the FIVB, and whose suspenion was lifted in May 2018) participated in the tournament, with Thailand already qualified as host country. Eight of the teams participated in the 2017 Asian Girls' U18 Volleyball Championship, while three did not participate in that previous edition. The thirteen AVC member associations were from four zonal associations, namely, Central Asia (3 teams), East Asia (5 teams), Oceania (2 team) and Southeast Asia (2 teams). No West Asian teams participated in this edition.
This was the first Asian Women's U17 Volleyball Championship to use the new competition format. Following the 2017 AVC Board of Administration’s unanimous decision, the new format saw teams being drawn into three or four pools up to the total amount of the participating teams. Each team, as well as the host side, were assigned into a pool according to their previous ranking (2017 Asian Girls' U18 Volleyball Championship). As the three best-ranked teams were drawn in the same Pool A, the next best three contested in Pool B, and the next best three contesting in Pool C. Pool D comprised teams that finished as the next best four teams.
Players born on or after 1 January 2002 were eligible to compete in the tournament. Each team were made to register a squad of 12 players from 19 players of their preliminary squad, per Regulations Articles 4.5, 4.6, 5.4 and 5.5.
