Biography of Athina Onassis

Early Life and Family Background

Athina Onassis was born into a family that, at one time, was among the most powerful and wealthiest in the world. Her grandfather, Aristotle Onassis, built a shipping empire that made him one of the richest men on the planet. He was also known for his marriage to Jacqueline Kennedy Onassis, the former First Lady of the United States.

Athina’s mother, Christina Onassis, was Aristotle’s only child. However, Christina passed away when Athina was just 11 years old, leaving her a vast inheritance and an even bigger legacy to live up to. Raised primarily in France, Athina grew up with immense wealth but also under the weight of her family’s tragic history and media scrutiny.

Her father, Thierry Roussel, was a French businessman, and the couple divorced when Athina was young. She was later raised by her maternal grandmother, Athina Livanos, and spent much of her childhood between France and Greece. Despite the luxury, her early life was marked by loss, isolation, and a growing desire to live life on her own terms.

Athina’s Career and Equestrian Passion

While many heirs might rest on their family’s wealth and reputation, Athina has pursued a career in equestrian sports. She’s an accomplished show jumper and has trained with some of the best in the sport. Her passion for horses is more than just a hobby—it’s a lifelong commitment.

She’s been involved in international competitions and owns several horses. Her equestrian career has given her a sense of identity beyond being an Onassis heir, and it’s one of the few areas where she’s allowed the public a glimpse into her world.

In addition to riding, Athina has shown interest in business ventures. One notable investment is in a French supermarket chain, which she funded in recent years. This move signals her desire to not just preserve her wealth but to grow it through smart, strategic investments.

Net Worth and Financial Overview

Athina Onassis inherited a staggering sum from her mother—reportedly around $800 million—and over time, through investments and careful management, her fortune has grown to an estimated $2.7 billion. She’s one of the wealthiest individuals in Europe and one of the youngest billionaires globally, though she rarely talks about her financial status publicly.

Her wealth comes from a mix of inherited assets, including real estate, yachts, and business holdings, as well as savvy financial decisions. She reportedly fought legal battles to gain full control of her fortune from her father, who had been managing it during her younger years. That victory allowed her to take charge of her legacy and make independent financial choices.

Though she lives a life of luxury, Athina has been careful not to flaunt her wealth. She lives quietly in Switzerland with her children and avoids the paparazzi and tabloid culture that often surrounds high-profile heirs.

Personal Life and Divorce Scandal

Athina married Brazilian show jumper Alvaro de Miranda Neto, known as “Doda,” in 2011. The couple had three daughters together but eventually divorced after several years of marriage. The split was not quiet—there were rumors of infidelity on Doda’s part, and the divorce proceedings were messy and public.

Despite the scandal, Athina has kept most of the details of her personal life private. She rarely gives interviews, and when she does, she avoids discussing her past relationships or the drama that came with them. Her focus seems to be on raising her children and maintaining a peaceful life away from the chaos of celebrity culture.

Her children are her top priority, and she’s been spotted attending equestrian events with them, passing on her love for the sport. She’s also been seen with her partner, a Swiss businessman, though details about their relationship remain minimal.

Rare Public Appearances in 2025

In 2025, Athina made a surprising return to public life. After years of seclusion, she attended the Friends of the Pompidou Center dinner in Paris in March. Dressed in a stunning red gown, she turned heads and sparked speculation about what’s next for her.

That wasn’t the only appearance—she also showed up at the Bal d’Été in Paris in July, again wearing red and looking more refreshed than in years past. Her appearances were widely covered by European media, and fans couldn’t help but notice how she looked almost unrecognizable compared to photos from earlier in her life.

Some have speculated that these appearances mark the beginning of a new chapter for Athina—possibly one where she steps more into the public eye, whether for charity work, business ventures, or simply embracing her role as the last Onassis heir.

The Onassis Legacy and Athina’s Place in It

The Onassis name is synonymous with old money, power, and tragedy. From Aristotle’s rise in the shipping industry to the Kennedy marriage and the untimely deaths of Christina and her brother Alexander, the family has lived through both immense success and heartbreak.

Athina is the only living descendant of Aristotle Onassis, and with that comes a responsibility to preserve the family’s legacy. She’s taken steps to manage her inheritance wisely and has started to engage in public life again, suggesting she may be ready to take on a more visible role in the Onassis story.

While she hasn’t made any major announcements about philanthropy or business expansions, her recent appearances hint at a shift. Whether she’ll continue to step into the spotlight or retreat again into privacy remains to be seen. For now, the world watches and waits, hoping for more glimpses of the last Onassis heir.
