Calvin Andre "C.J." Miles, Jr. (born March 18, 1987 in Dallas, Texas) is an American professional basketball player, drafted by the Utah Jazz with the 34th pick of the 2005 NBA Draft. He is from Skyline High School in Dallas and plays shooting guard. He committed to the University of Texas at Austin, stating that if he was not selected in the first round of the NBA Draft he would attend the school. Miles later changed this decision after the Jazz offered a two-year guaranteed contract equivalent to that of a late first round selection.

During the 2005-06 season, the Jazz assigned Miles to the Albuquerque Thunderbirds of the NBA Development League (D-League) in order for him to attain more experience.

After playing 21 games during the 2006-07 NBA season, he was again assigned by the Jazz to the D-League, this time to the Idaho Stampede.

Miles is perhaps best known as the subject of one of the most memorable post-game interviews of the 2006-07 NBA season, where coach Jerry Sloan stated, "I don't care if he's 19 or 30. If he's going to be on the floor in the NBA, he's got to be able to step up and get after it. We can't put diapers on him one night, and a jockstrap the next night. It's just the way it is." Miles at the time was the youngest player on the Jazz roster.

Miles has seen limited playing time in his first 3 seasons with the Jazz, occasionally being sent down to the NBA Development League in his first two seasons. His impressive preseason showing gave him the starting job in the 2006-07 NBA season, which he quickly lost. After Gordan Giricek was removed from the Jazz's lineup partway through the 2007-08 NBA season, his playing time increased significantly and he showed significant signs of improvement, although since Kyle Korver has arrived his playing time has again decreased.
