Jacqueline Lee Bouvier, detta Jackie (Jackie Kennedy, durante il primo matrimonio, Jackie O, durante il secondo), coniugata Kennedy in prime nozze e Onassis in seconde nozze (Southampton, 28 luglio 1929 – New York, 19 maggio 1994), è stata una first lady statunitense.

Fu la moglie di John Fitzgerald Kennedy, 35º presidente degli Stati Uniti, First Lady dal 20 gennaio 1961 al 22 novembre 1963, data dell’assassinio del marito. Vedova, sposò poi l’armatore greco Aristotele Onassis.

Jacqueline Lee “Jackie” Kennedy Onassis (née Bouvier, pronounced /ˌˈdʒækliːn ˈliː ˈbuːvieɪ/; July 28, 1929 – May 19, 1994) was the wife of the 35th President of the United States, John F. Kennedy, and First Lady of the United States during his presidency from 1961 until his assassination in 1963. Five years later, she married Greek shipping magnate Aristotle Onassis; they remained married until his death in 1975.

Jacqueline was the elder daughter of Wall Street stockbroker John Vernou Bouvier III and socialite Janet Norton Lee, who divorced in 1940. In 1951, she graduated with a Bachelor of Arts degree in French literature at George Washington University and went on to work for the Washington Times-Herald as an Inquiring Photographer.

In 1952, Jacqueline met Congressman John F. Kennedy at a dinner party. Shortly after, he was elected to the United States Senate and the couple married the following year. They had four children, two of whom died in infancy. As First Lady, she aided her husband’s administration with her presence in social events and with her highly publicized restoration of the White House. On November 22, 1963, she was riding with her husband in a motorcade in Dallas, Texas, when he was assassinated. She and her children withdrew from public view after his funeral, and she remarried in 1968 after the assassination of Robert F. Kennedy.

Following her second husband’s death, for the final two decades of her life, Jacqueline Kennedy Onassis had a career as a book editor. She is remembered for her contributions to the arts and preservation of historic architecture, as well as for her style, elegance, and grace. She was a fashion icon; her famous ensemble of pink Chanel suit and matching pillbox hat has become symbolic of her husband’s assassination and one of the lasting images of the 1960s. She ranks as one of the most popular First Ladies and in 1999 was named on Gallup’s list of Most Admired Men and Women in 20th century America.
