Athina Onassis is one of the richest from France. According to our analysis, Wikipedia, Forbes & Business Insider, Athina Onassis's net worth $1 billion (2019 estimate). (Last Update: December 11, 2023)
Athina Onassis is the sole heiress of Christina Onassis, who inherited 55% of Aristotle Onassis’s fortune. The remaining 45% of Aristotle’s fortune (minus $26 million settled upon Jacqueline Kennedy Onassis) was left to the Alexander S. Onassis Foundation, established in honor of Alexander Onassis, Athina’s late uncle, who had died in 1973. When Athina Onassis was seven years old, the New York Times cited a report from the Associated Press, naming Onassis one of the year’s new billionaires, and even though she is often credited as a “billionaire heiress” throughout the media, the true extent of her wealth remains unknown. There have been several estimates of her inheritance, including the island of Skorpios, which was later sold to trusts connected with Ekaterina Rybolovleva, with some accounts claiming that Onassis’s net worth is less than $1 billion.
Onassis has three half-siblings, via her father’s relationship with Landhage: Erik Christopher Roussel (born July 1985), Sandrine Roussel (born May 1987), and Johanna Roussel (born July 1991).
Onassis is a competitive show jumper in select events of the Global Champions Tour. She began riding as a child, and finished second in an event in Jerez, Spain in 2001. She later chose to compete as a Greek citizen for the Avlona Riding Club in Athens, under the name “Athina Onassis”. In November 2012, Onassis suffered a spinal injury in a fall from her horse, but was reported to be returning to competition in January 2013. She represented Greece in the 2013 European Show Jumping Championships and the 2014 World Championships.
