The World Team Cup was the international men's team championship of the Association of Tennis Professionals (ATP). The inaugural edition of the tournament was contested in 1975 in Kingston, Jamaica and was called the Nations Cup. No tournament was held in 1976 and 1977. From 1978 through 2012 the tournament was held annually in Düsseldorf, Germany. It was generally considered to be second most prestigious men's team competition in tennis after the Davis Cup.
