The 1974 Davis Cup was the 63rd edition of the Davis Cup, the most important tournament between national teams in men's tennis. 57 teams would enter the competition, 33 in the Europe Zone, 12 in the Americas Zone, and 12 in the Eastern Zone. Nigeria made its first appearance in the tournament. South Africa defeated Colombia in the Americas Inter-Zonal final, India defeated Australia in the Eastern Zone final, and Italy and the Soviet Union were the winners of the two Europe Zones, defeating Romania and Czechoslovakia respectively. In the Inter-Zonal Zone, South Africa defeated Italy and India defeated the Soviet Union in the semifinals. India refused to travel to South Africa for the final due to their government's opposition to South Africa's apartheid policies: therefore, the final was scratched and South Africa were awarded the Davis Cup. South Africa became only the fifth nation to win the Davis Cup, breaking the dominance of the United States, Great Britain, France and Australia teams which had won every tournament before this year.
