The 1959 Davis Cup was the 48th edition of the Davis Cup, the most important tournament between national teams in men's tennis.

The Europe Zone was modified so that only the previous year's semifinalists were guaranteed first round byes, allowing more countries to compete.

Australia defeated Cuba in the Americas Inter-Zonal final, India defeated the Philippines in the Eastern Zone final, and Italy defeated Spain in the Europe Zone final.

In the Challenge Round Australia defeated the defending champions the United States.

The final was played at the West Side Tennis Club in Forest Hills, New York, United States on 28–31 August.
