The Europe/Africa Zone is one of the three zones of the regional Davis Cup competition in 1989.
In the Europe/Africa Zone there are two different tiers, called groups, in which teams compete against each other to advance to the upper tier.
Winners in Group I advanced to the World Group qualifying round, along with losing teams from the World Group first round. Teams who lost in the first round competed in the relegation play-offs, with winning teams remaining in Group I, whereas teams who lost their play-offs were relegated to the Europe/Africa Zone Group IIs in 1990.
The winner in the Europe Zone Group II advanced to the Europe/Africa Zone Group I in 1990.
