The 1923 International Lawn Tennis Challenge was the 18th edition of what is now known as the Davis Cup.

This change was necessitated by having more than 16 teams compete for the cup (thus not fitting into one easily workable draw).

The past several years had also seen a rise in the number of defaults, as teams from around the globe tried to work out the logistics of playing such an international tournament.

Australia defeated France in the Inter-Zonal play-off, but again lost to the United States in the Challenge Round.

The final was played at the West Side Tennis Club in New York City on 31 August – 3 September.
