Stavros Spyros Niarchos (Greek: Σταύρος Σπύρος Νιάρχος, Greek pronunciation: [ˈstavros ˈspiros niˈarxos]; 3 July 1909 – 16 April 1996) was a Greek shipping tycoon and multi-billionaire. In 1952, Stavros Niarchos built the biggest supertankers capable of transporting large quantities of oil, and subsequently earned millions of dollars as global demand for his ships increased.
Early life 
He was born in Athens, son of Spyros Niarchos and his wife, Eugenia Coumandaros. His parents were naturalized Americans and had owned a department store in Buffalo, New York before returning to Greece, three months prior to his birth. He studied law at the University of Athens, after which he went to work in the Coumandaros family's grain business. During this period, he became involved in shipping by convincing his relatives that greater profits could be achieved if the firm owned the ships involved.
Shipping successes 
He was a naval officer in World War II, during which time part of the trade fleet he had developed with his uncle was destroyed. He used about two million dollars in insurance money to build a new fleet, and he was the owner of the yacht Atlantis.
Stavros Niarchos founded Niarchos Ltd., an international shipping company that at one time operated more than 80 tankers worldwide. He and Aristotle Onassis were great shipping rivals. The first supertankers capable of transporting large quantities of oil were built in 1952 for the competing Niarchos and Onassis fleets. In 1955 Vickers Armstrongs Shipbuilders Ltd launched for Stavros Niarchos what was then the World's largest supertanker. The 30,708 GRT ship was named SS Spyros Niarchos after Niarchos' second son, Spyros, who was born that year.
- His first marriage, in 1930, to Helen Sporides, a daughter of Admiral Constantine Sporides, lasted one year.
- His third wife was Eugenia Livanos, a daughter of shipping magnate Stavros G. Livanos. They married in 1947 and divorced in 1965; she died in 1970 at the age of 44, after an overdose of barbiturates.

The marriage ended in divorce the following year (1967), whereupon Niarchos returned to his former wife, Eugenia. No remarriage was necessary, since the couple's 1965 Mexican divorce was not recognized in Greece. 
- In 1971, Niarchos married his wife Eugenia's sister, Athina, Marchioness of Blandford, who had been the first wife of Aristotle Onassis. She died of an overdose in 1974.

Thoroughbred horse racing 
|This section requires expansion. (January 2007)|
Stavros Niarchos began investing in thoroughbred horse racing in the early 1970s when he put together a highly successful stable of racehorses that competed in France and the United Kingdom. He eventually acquired the Haras de Fresnay-le-Buffard horse breeding farm in Neuvy-au-Houlme, France and Oak Tree Farm in Lexington, Kentucky where in 1984 he bred his most successful horse, Miesque. Niarchos was the leading owner in France twice (1983, 1984) and topped the breeders' list three times (1989, 1993, 1994).
After his death in 1996, his daughter Maria Niarchos-Gouazé took charge of the racing operations. She continued to build on his success, and in 2004 her colt Bago won France's most important race, the Prix de l'Arc de Triomphe, and in 2005 her filly Divine Proportions won the Prix de Diane Hermes winning 9 out of her 10 races until her racing career finished with a serious tendon injury.
