The U.S. Men’s Clay Court Championships is an annual ATP Tour tennis tournament. It was founded in 1910 and has been held in nearly two dozen cities. Since 2001, it has been held in Houston, Texas. It is the only remaining ATP World Tour-level tournament in the United States to be played on clay courts. 

Between 1970 and 1989, it was part of the Grand Prix Tennis Tour as part of the Grand Prix Super Series of events (1974–1977). During the stint in Indianapolis, from 1969 through 1986, the tournament was a combined men’s and women’s event. From 2001 to 2007, the event was held at the Houston Westside Tennis Club. 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. But in May 2007, the USTA announced that the tournament would simply move downtown to River Oaks Country Club in the River Oaks neighborhood. The new venue has a stadium with seating for 3,000 with temporary seating for 500 for the second court. Its Har-Tru clay, of a maroon color, was renewed in 2005 and 2008.

Bill Tilden holds the record for most titles (7). Bill Tilden and Frank Parker share the record of most finals (8). The current champions are Frances Tiafoe in singles and Max Purcell and Jordan Thompson in doubles.
