2018 Men's Asian U18 Volleyball Championship

The 2018 Men's Asian U18 Volleyball Championship was the 12th edition of the Men's Asian U18 Volleyball Championship, a biennial international volleyball tournament organised by the Asian Volleyball Confederation (AVC), that year with the Islamic Republic of Iran Volleyball Federation (IRIVF). The tournament was held in Tabriz, Iran from 29 June to 6 July 2018. The top four teams of the tournament qualified for the 2019 FIVB Volleyball Boys' U19 World Championship as AVC's representatives.

To participate, players must have been born on or after 1 January 2001, and they could only enroll for a maximum of one championship.

On 14 December 2020, the AVC announced that the 2020 Men's Asian U18 Volleyball Championship, which was originally the AVC qualifier for the 2021 FIVB Volleyball Boys' U19 World Championship, was canceled due to the COVID-19 pandemic, and that the top four teams of the 2018 tournament that had not yet qualified to the 2021 U19 World Championship would now be qualified for the same Championship as AVC's representatives.

The 18 AVC member associations submitted their U18 men's national teams to the Championship; however, Uzbekistan later withdrew. The 17 AVC member associations were from 5 zonal associations, including, Central Asia (6 teams), East Asia (5 teams), Oceania (2 teams), Southeast Asia (2 teams) and West Asia (2 teams).

Pools composition
This was the first Asian U18 Championship to use the new competition format. Following the 2017 AVC Board of Administration's unanimous decision, the new format saw teams drawn into six pools up to the total amount of the participating teams. Each team, including the hosts, was assigned into a pool according to their final standing in the 2017 edition. As the three best ranked teams were drawn in the same pool A, the next best three contested pool B, and the next best three contested pool C. Uzbekistan withdrew after the draw. The teams' final standing in the 2017 edition are shown in brackets.
