Ireland competed in its first Davis Cup in 1923.

Ireland currently compete in the World Group Zone II, having been promoted from Europe Zone Group III in 2021.

They competed in World Group in 1983, and also reached the semifinals of the Europe Zone in 1936.

Players from Northern Ireland are, controversially for some, designated as holding Irish nationality by the International Tennis Federation, effectively compelling them to represent Ireland rather than Great Britain in international tennis competitions and the Olympic Games.
