Early life
Gauff was born at West Boca Medical Center in Boca Raton, Florida, on March 13, 2004, to Candi (née Odom) 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 age 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' [tournament] 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.

Playing style and coaching
While hard court is Gauff's favorite surface, she has yielded her best results on clay.

From July 2023 to September 2024 her coach was Brad Gilbert. Gilbert encouraged Gauff to put high, heavy topspin on her ball and to chase down balls in every corner of the court. In September 2024 Gauff hired coach Matt Daly, who has focused on improving her serve and forehand with a grip on her racket that is closer to the eastern backhand style rather than the more frequently used continental style. In August 2025, Gauff replaced Daly with Gavin MacMillan, a biomechanics specialist who helped rescue Aryna Sabalenka's serve.

Personal life
Gauff is a Christian. Since she was eight years old, she has prayed with her father before every match that she and her opponent would be safe. After winning the Cincinnati Open in August 2023, she said: "... I'd like to thank my Lord and Savior, Jesus Christ. I spent a lot of nights alone, crying trying to figure it out. I still have a lot to figure out, but I thank Him for covering me." After winning her first major title in September 2023, she said: "... I don't pray for results, I just ask that I get the strength to give it my all and whatever happens happens. I'm so blessed in this life."
Gauff's tennis idols are Serena and Venus Williams. "Serena Williams has always been my idol...and Venus," she has said. "They are the reason why I wanted to pick up a tennis racquet." Gauff first met Serena when she won the Little Mo' national tournament at the age of eight, and later met her again to film a commercial for Delta Air Lines and at the Mouratoglou Academy. After defeating Venus Williams at Wimbledon in 2019, Gauff expressed her respect when they shook hands at the net. "I was just telling her thank you for everything she's done for the sport," Gauff said. "She's been an inspiration for many people. I was just really telling her thank you."
