The 1933 International Lawn Tennis Challenge was the 28th edition of what is now known as the Davis Cup.

The United States defeated Argentina in the America Inter-Zonal Final, and Great Britain defeated Australia in the Europe Zone final.

In the Inter-Zonal play-off Great Britain defeated United States, and went on to defeat France in the Challenge Round.

Great Britain's victory ended France's six-year run as champions and gave the Great Britain team their first title since 1912.

The final was played at Stade Roland Garros in Paris on 28–30 July.
