The 1992 Davis Cup was the 81st edition of the Davis Cup, the most important tournament between national teams in men's tennis. 93 teams would enter the competition, 16 in the World Group, 21 in the Americas Zone, 23 in the Asia/Oceania Zone, and 33 in the Europe/Africa Zone. Due to the increased number of entries, the tournament was expanded to add a Group III in all zones, with promotion and relegation between it and Group II. Puerto Rico and Qatar made their first appearances in the tournament, and former champions South Africa returned to the tournament for the first time since 1978.
