How Old Is Serena Williams' Daughter? Olympia, 9 (2026)

The Short Answer: Olympia Is 9

Serena Williams’ older daughter is 9 years old. Alexis Olympia Ohanian Jr. was born on September 1, 2017, at St. Mary’s Medical Center in West Palm Beach, Florida, after an emergency cesarean. As of October 2026, she is 9 — she celebrated her 9th birthday on September 1, 2026.

Her little sister, Adira River Ohanian, was born in August 2023 and is 3. The family announced Adira’s arrival on August 23, 2023, via Instagram and TikTok; the exact birth date was not publicly disclosed by the family. Together, Olympia (9) and Adira (3) are the two daughters of Williams and Alexis Ohanian.

Alexis Olympia Ohanian Jr.: Born September 1, 2017

Olympia’s birth was dramatic. Williams’ heart rate plummeted during labor, prompting an emergency C-section; post-surgery, she suffered a life-threatening pulmonary embolism that required multiple surgeries and a six-day hospital stay. Williams later turned the trauma into advocacy for maternal health — particularly for Black mothers.

Nine years later, Olympia — “Junior” to her family — is a personality in her own right: a piano student, a golf-lesson taker, a Paris Fashion Week companion, and, per her mother, a naturally gifted tennis player who prefers ballet and creative pursuits. She graced the cover of Vogue with her mom in 2022, and in 2026 she became, improbably, her mother’s coach — the 9-year-old whose suggestion sent Serena back to Wimbledon.

“My daughter, Olympia, told me I should play with Venus,” Williams said in June 2026. “She’s always right, so I was like, okay.”

Adira River Ohanian: Born August 2023

Adira River Ohanian was born in August 2023 — Williams revealed the pregnancy that May at the Met Gala, then introduced her second daughter on August 23, 2023, with Ohanian writing on Instagram that their house was “teaming with love: a happy & healthy newborn girl and happy & healthy mama.”

The family has not publicly disclosed Adira’s exact birth date, and published reports differ — so the verified fact is the month: August 2023. She is 3 as of October 2026. Her name means “strong and mighty,” and Ohanian has lovingly dubbed Williams the “GMOAT” — Greatest Mother of All Time — since her arrival.

Adira’s birth fulfilled the plan Williams laid out when she “evolved away” from tennis after the 2022 US Open: to grow her family. Olympia, who had long wished for a sibling, took to big-sisterhood with pride.

The Dad: Alexis Ohanian

Alexis Ohanian, the Reddit co-founder turned investor, met Williams by chance over breakfast in Rome — she told him to sit beside her, and the rest is history. He proposed on December 10, 2016; they married on November 16, 2017, at the Contemporary Arts Center in New Orleans, about ten weeks after Olympia’s birth.

Ohanian has become one of sport’s most visible “girl dads”: a leading investor in women’s sports (Angel City FC, a stake in Chelsea F.C. Women), creator of the all-female track series Athlos, and a relentlessly present father who posts pancake breakfasts, book readings, and pink-restaurant outings with Olympia and Adira. “Girl dads live longer,” he likes to say.

He frequently credits Williams’ strength — and describes fatherhood, which began for him on September 1, 2017, as the role that changed his life.

2026: The Comeback (at Olympia’s Request)

In 2026, Serena Williams did what she said she’d never do: she came back. Nearly four years after the 2022 US Open, the 44-year-old returned to competition in doubles — first at the HSBC Championships at Queen’s Club (winning her first match back alongside Victoria Mboko), then at the Berlin Open with Karolina Muchova.

Then came Wimbledon. The sisters received a wild card into the women’s doubles draw at the 2026 Championships — and Wimbledon also handed Serena a singles wild card, her first Grand Slam singles match since 2022. She fell in the singles first round, then opened doubles with Venus — the 14-time Grand Slam doubles champions, six of them at Wimbledon, back on Centre Court’s grass.

The reason, Williams said, was sitting courtside: “It’s really about my kids getting to see me play,” she said in June 2026. “Olympia is a little bit older; Adira is very young.” She played Wimbledon and the US Open in August 2026 — and at 44, with 23 Grand Slam singles titles, she has not said whether the comeback continues.

October 2026: A Barbie, 25 Years in the Making

On October 8, 2026 — timed to International Day of the Girl — Mattel officially released the Barbie Signature Serena Williams Doll. The collectible recreates her iconic 2005 Australian Open look: the neon green-and-white mesh cutout top, white skirt, sweatband, tennis shoes, racket, and ball — the outfit from the title run where she saved match points against Maria Sharapova and won her seventh Grand Slam.

It is her second Barbie of 2026 (a one-of-a-kind Role Model doll arrived in March for International Women’s Day) and the latest chapter in a quarter-century partnership stretching back to a 1999 doll. The $45 collectible includes a Dream Gap Project donation to Mrs. Rina’s House of Blessings in Florida, chosen by Williams herself.

“I want every girl who plays with this doll to see possibility — not just in me, but in herself,” Williams said. Somewhere in Florida, a 9-year-old named Olympia presumably agrees.

Mom of Two: Serena’s Second Act

Williams has said motherhood changed her “in many good ways” — and reshaped her ambitions. The tennis comeback, the Barbie, the business empire (Serena Ventures): all of it now runs through the lens of two girls, 9 and 3, who call her Mom.

Olympia, the tennis-prodigy-turned-ballet-lover who talked her mother into a Wimbledon reunion, and Adira, the calm, warm-energy 3-year-old growing up in her sister’s wake — together they are the reason Williams says she plays at all anymore. “It’s really about my kids getting to see me play,” she said. One last time, or the start of something longer: at 44, Serena Williams — 23-time Grand Slam champion, Barbie honoree, and mom of Olympia and Adira — hasn’t decided. As of October 2026, the ball is in her court.

Olympia in the Spotlight

For a 9-year-old, Olympia Ohanian has range. She covered Vogue with her mom in 2022 in matching outfits; she takes piano and golf lessons; she’s been her mother’s Paris Fashion Week companion. Serena calls her “best helper” and praises her “bright, happy spirit” — and notes, with amusement, that despite obvious natural talent, Olympia prefers ballet and music to tennis.

Then there’s the coaching. It was Olympia who planted the Wimbledon doubles idea — “Mom, you should play with Venus,” delivered, per Serena, with total seriousness: “She’s very smart. She’s very wise, I think, is a better word.” The 9-year-old’s scouting report proved correct: the reunion became the story of the summer.

The 2026 Season, Match by Match

The comeback unfolded in stages. First the HSBC Championships at Queen’s Club, where Williams and Victoria Mboko won their first match back — vintage Serena, including a backhand winner on the run. Then the Berlin Open with Karolina Muchova, a first-round loss. Then Wimbledon: a singles wild card and a doubles wild card with Venus — the sisters’ first Grand Slam doubles together since their 14-0 finals record was built.

The singles run ended in round one against Australia’s Maya Joint, 6-3, 6-7(6), 6-3 — Williams’ first singles match since the 2022 US Open. She then played the US Open in August 2026 and has not competed since, leaving the question open. At 44, with 23 Grand Slam singles titles and two daughters watching, Serena Williams’ 2026 was never really about the results — it was about Olympia and Adira getting to see Mom play, “one last time” or otherwise.
