The Europe/Africa Zone is one of the three zones of the regional Davis Cup competition in 2018. In the Europe/Africa Zone there are three different tiers, called groups, in which teams competed against each other to advance to the upper tier. Winners in Group II advance to the Europe/Africa Zone Group I. Teams who lose their respective ties competed in the relegation play-offs, with winning teams remaining in Group II, whereas European and African teams who lose their play-offs are relegated respectively to the Europe and Africa Zone Group III in 2019.
