Early life
Gauff was born at West Boca Medical Center in Boca Raton, Florida, on March 13, 2004, to Candi and Corey Gauff, both from Delray Beach. She has two younger brothers. Her father played college basketball at Georgia State University and later worked as a health care executive. Her mother was a track-and-field athlete at Florida State University and worked as an educator. Gauff lived her early years in Atlanta. She began playing tennis at the age of six. When she was seven, her family moved back to Delray Beach to have better training opportunities. She worked with Gerard Loglo at the New Generation Tennis Academy starting from the age of eight.Gauff recalled, "I wasn't much of a team person. I loved tennis. I was so-so about it in the beginning because when I was younger I didn't want to practice at all. I just wanted to play with my friends. When I turned eight, that was when I played 'Little Mo' and after that I decided to do that for the rest of my life."
Gauff's parents gave up their careers to focus on training their daughter. Her father later became her primary coach, while her mother oversaw her homeschooling. Her father had limited experience playing tennis growing up. At the age of 10, Gauff began to train at the Mouratoglou Tennis Academy in France run by Patrick Mouratoglou, longtime coach of Serena Williams. Mouratoglou commented, "I'll always remember the first time I saw Coco. She came over to the Mouratoglou Academy in 2014 to try out and she impressed me with her determination, athleticism and fighting spirit.... When she looks at you and tells you she will be number one, you can only believe it." He helped sponsor Gauff through his Champ'Seed foundation, which he created to provide funding for talented juniors who did not have the financial resources to afford high-level training.
Gauff won the USTA Clay Court National 12-and-under title at the age of 10 years and three months to become the youngest champion in the tournament's history.
