The Eastern Zone was one of the three regional zones of the 1964 Davis Cup.
10 teams entered the Eastern Zone, with the winner going on to compete in the Inter-Zonal Zone against the winners of the America Zone and Europe Zone. With the increase in entries, the Eastern Zone was split into two sub-zones, with the winner of each sub-zone playing to determine which team moved to the Inter-Zonal Zone.[1]
The Philippines defeated Japan in the Zone A final, and India defeated South Vietnam in the Zone B final. In the Inter-Zonal final the Philippines defeated India and progressed to the Inter-Zonal Zone.
