John Fitzgerald Kennedy, Jr. (November 25, 1960 – July 16, 1999), often referred to as John F. Kennedy, Jr., JFK Jr., John Jr. or John-John, was an American socialite, magazine publisher, lawyer, and pilot. The elder son of U.S. President John F. Kennedy and First Lady Jacqueline Lee Bouvier Kennedy, Kennedy died in a plane crash along with his wife Carolyn Bessette-Kennedy and his sister-in-law Lauren Bessette, on July 16, 1999.

John F. Kennedy, Jr. was born at Georgetown University Hospital sixteen days after his father was elected to the presidency. The younger Kennedy was in the public spotlight from his father's inauguration as President of the United States in 1961 until his own death in 1999. He had an older sister, Caroline, and a younger brother, Patrick, who died two days after birth in 1963. For most of the first three years of his life, he lived in the White House. His nickname "John-John" came from a reporter who misheard JFK calling him ("John" spoken twice in quick succession). Though he was often referred to publicly as "John-John", members of the Kennedy family themselves did not use the nickname.
