The U.S. Men's Clay Court Championships is an annual ATP Tour tennis tournament.

[2] It is the only remaining ATP World Tour-level tournament in the United States to be played on clay courts.

The tournament began in 1910 when the Western Lawn Tennis Association (a section of the United States Lawn Tennis Association now known as the USTA/Midwest) persuaded the USLTA that a National Clay Court Championship would promote the construction of more clay courts in the West.

The first National Clay Court Championships were held at the Omaha Field Club; a crowd of 5,000 watched the finals.

In 2007, the U.S. Tennis Association sought a new venue and entertained bids from Atlanta, Georgia; Winston-Salem, North Carolina; and Ponte Vedra Beach, Florida.
