Which country has won the most Davis Cup titles in tennis history?

The United States has won the most Davis Cup titles in tennis history. The American team has lifted the trophy 32 times, more than any other nation, with Australia second on 28 titles.

The competition began in 1900 as the International Lawn Tennis Challenge after American tennis player and politician Dwight F. Davis donated the trophy. The inaugural tie was contested by the United States and Great Britain, and the Americans won the first championship.

Davis Cup tennis is a team competition rather than an individual tournament. Players represent their countries in singles and doubles rubbers, and the team winning the required majority advances or claims the title. The United States dominated especially during the early and mid-20th century, producing champions such as Bill Tilden, Don Budge, Pete Sampras, and John McEnroe. Its most recent title came in 2007, when the team defeated Russia.
