2023 ITF Men's World Tennis Tour (October–December)

The 2023 ITF Men's World Tennis Tour is the 2023 edition of the second-tier tour for men's professional tennis. It is organised by the International Tennis Federation and is a tier below the ATP Challenger Tour. The ITF Men's World Tennis Tour includes tournaments with prize money ranging from $15,000 to $25,000.

Since 2022, following the Russian invasion of Ukraine, the ITF announced that players from Belarus and Russia could still play on the tour but would not be allowed to play under the flag of Belarus or Russia.
