The Americas Zone was one of the three regional zones of the 1975 Davis Cup.
Twelve teams entered the Americas Zone split across two sub-zones, the North & Central America Zone and the South America Zone. Nine teams played in the preliminary rounds, competing to advance to the main draw and join the remaining three teams who advanced to the main draw directly. The winners of each sub-zone main draw then played against each other to determine who moved to the Inter-Zonal Zone to compete against the winners of the Eastern Zone and Europe Zone.
South Africa were declared winners of the North & Central America Zone by walkover after Colombia withdrew ahead of the final, while in the South America Zone Chile defeated Brazil in the final. In the Americas Inter-Zonal Final, Chile defeated South Africa and progressed to the Inter-Zonal Zone.
