The Americas Zone was one of the three regional zones of the 1973 Davis Cup.
12 teams entered the Americas Zone split across two sub-zones, the North & Central America Zone and the South America Zone. 5 teams played in each of the sub-zone's preliminary rounds, with two teams progressing to each sub-zone's main draw to join the previous year's finalists the United States and Chile. 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. [1]
The United States defeated Mexico in the North & Central America Zone final, and Chile defeated Argentina in the South America Zone final. [2] [3] In the Americas Inter-Zonal Final, the United States defeated Chile and progressed to the Inter-Zonal Zone. [4]
