The Americas Zone is one of the three zones of the regional Davis Cup competition in 2016.
In the Americas Zone there are three different tiers, called groups, in which teams compete against each other to advance to the upper tier. Winners in Group II advance to the Americas Zone Group I. Teams who lose their respective ties will compete in the relegation play-offs, with winning teams remaining in Group II, whereas teams who lose their play-offs will be relegated to the Americas Zone Group III in 2017.
