The Asia/Oceania Zone was one of the three zones of the regional Davis Cup competition in 2018.
In the Asia/Oceania Zone there were four different tiers, called groups, in which teams competed against each other to advance to the upper tier. Winners in Group II advanced to the Asia/Oceania Zone Group I. Teams who lost their respective ties competed in the relegation play-offs, with winning teams remaining in Group II, whereas teams who lost their play-offs were relegated to the Asia/Oceania Zone Group III in 2019.
