- Source: 1978 Davis Cup Europe Zone
The Europe Zone was one of the three regional zones of the 1978 Davis Cup.
29 teams entered the Europe Zone, competing across 2 sub-zones. 25 teams entered the competition in the qualifying round, competing for 4 places in each sub-zone's main draw to join the 4 finalists from the 1977 Europe Zone. The winners of each sub-zone's main draw went on to compete in the Inter-Zonal Zone against the winners of the Americas Zone and Eastern Zone.
Great Britain defeated Czechoslovakia in the Zone A final, and Sweden defeated Hungary in the Zone B final, resulting in both Great Britain and Sweden progressing to the Inter-Zonal Zone.
