1991 Davis Cup

The 1991 Davis Cup (also known as the 1991 Davis Cup by NEC for sponsorship purposes) was the 80th edition of the Davis Cup, the most important tournament between national teams in men's tennis. 88 teams would enter the competition, 16 in the World Group, 20 in the Americas Zone, 20 in the Asia/Oceania Zone, and 32 in the Europe/Africa Zone. Congo, the Eastern Caribbean, El Salvador and Saudi Arabia made their first appearances in the tournament.

This year's tournament saw the Germany Davis Cup team representing all parts of Germany for the first time since 1939, following the reunification of West and East Germany into a single German state in October 1990. The breakup of Yugoslavia during the tournament also resulted in impacts for the Yugoslavia Davis Cup team, after high-profile Croatian players Goran Ivanišević and Goran Prpić withdrew from the Yugoslav team following Croatia's declaration of independence in June 1991.

France defeated the United States in the final, held at the Palais des Sports de Gerland in Lyon, France, on 29 November–1 December, to win their first title since 1932 and their 7th title overall.
