American tennis star Coco Gauff comes from a family of athletes.
Her parents Corey and Candi Gauff, who have been married for over 20 years, are often by her side at tennis tournaments, as are her two brothers.
Coco Gauff told "Good Morning America" having her family support her no matter the outcome of her matches has been "amazing."
"The support that I have is amazing, and especially my parents, for them to sacrifice so much and come on the road and my brothers sacrificing time with their parents, because they end up being there for me in those big moments and being so understanding means the world," the tennis star said following her 2025 French Open win.
"I truly can't do it without them," she added. "Tennis is a lonely sport at times, spending weeks in different countries. Sometimes you don't wake up and know where you are, but you know, every night we're playing a card game, Crowns -- but every time I won, I felt like, 'OK, if I won the card games, maybe I'll win my match tomorrow.'"
The 21-year-old tennis phenomenon's parents have watched her make history over the years, including at the 2024 Olympics, where she became the youngest American woman to win a singles match at the Olympic Games since Venus Williams in 2000, according to ESPN.
Coco Gauff also made history when she carried the flag for Team USA, alongside NBA legend LeBron James, in the Games' opening ceremony, becoming the first tennis player to carry the flag for the U.S.
In 2023, when Coco Gauff won the U.S. Open, the first people she celebrated with and thanked were her parents.
"Thank you guys. You believed in me from the beginning," she said to her parents, adding of a special U.S. Open memory, "My dad took me to this tournament, sitting right there, watching Venus [Williams] and Serena [Williams] compete, so it's really incredible to win on this stage."
Here are five things to know about Coco Gauff and her family.
1. Both her parents were college athletes.
Coco Gauff has been praised for her athleticism on the court, and athleticism, it turns out, runs in her family.
Corey Gauff was a basketball player at Georgia State University, while Candi Gauff was a star heptathlete on the track and field team at Florida State University.
"Candi was a very well-rounded athlete. She did the multi events, which meant she had to run, jump, hurdle, throw, all those things," Terry Long, who coached Candi Gauff at FSU, told the Tallahassee Democrat in 2019.
Corey Gauff told the New York Times in 2019 that he believes he and his wife's collegiate experience helped them in raising their daughter.
"I think it helps parents when they have played as high as college or even pro," Corey Gauff said. "You better understand the process, and so you don't get too jittery about it. You don't feel like you're running out of time, so you are not rushed. You kind of meet your kid where they are at."
2. The family moved to Florida to help Coco's tennis career.
Coco Gauff was born in Atlanta, but as a child she moved with her family to Delray Beach, Florida, where they continue to live today, to further her tennis training.
3. Coco has two brothers.
Coco Gauff is not the only child in her family, as she has younger siblings, Codey Gauff and Cameron Gauff.
"My brothers are the reason why I [pursue tennis at a high level]," Coco Gauff told "GMA." "Codey always reminds me of the belief and kind of having that cockiness a little bit."
Gauff also added, "Cameron always reminds me to just be joyful in the things I do. So I truly learn a lot from everyone around me."
Cameron, a middle school student, plays tennis as well as basketball and football, according to Candi Gauff's Instagram account.

After her U.S. Open victory, Coco Gauff was seen on the court talking on her phone, which turned out to be a call with one of her brothers.
"I FaceTimed my brother, but he didn't answer," she said in the post-match interview, adding that he did call her back.
4. Coco's dad was her first tennis coach.
Though his athletic background was on the basketball court, not the tennis court, Corey Gauff took the lead in coaching his daughter early on.
He previously told the New York Times that he extensively studied the careers of other great tennis legends, including Venus and Serena Williams, be able to coach his daughter.
In 2023, Corey Gauff stepped back from coaching his daughter full-time and is now more of a support system for her, like her mom.
"They're just really my support system," Coco Gauff said last week at a news conference after winning her quarterfinal match at the U.S. Open. "They're helping me remember, you know, my clothes and everything, and my dad is still sending me scouting reports for every match. But my mom is more so, you know, just being mom. My dad just being dad other than the scouting report part."
5. Coco's parents saw her potential early on.
Both Corey and Candi Gauff have said previously that they exposed their daughter to many sports, but she quickly fell in love with -- and showed a real talent for -- tennis.
In a 2019 interview with "GMA," Candi Gauff said her daughter was still in a stroller when she saw she was "destined to be something."
