ATP International Series

Last updated July 11, 2025

The ATP International Series (known from 1990 to 1999 as the ATP World Series) was a series of professional tennis tournaments held internationally as part of the ATP Tour from 2000 to 2008.

The series was renamed ATP Tour 250 in 2009.^[1] International Series offered players cash prizes (tournaments have purses from $416,000 to $1,000,000) and the ability to earn ATP ranking points. They generally offered less prize money and fewer points than the ATP International Series Gold, but more than tournaments on the ATP Challenger Series.
