John Jacob Astor VI, born August 14, 1912 in New York, New York, United States - died June 26, 1992 in Miami Beach, Florida, was a member of the prominent Astor family. Note: Standard genealogies of the Astor family consider this man John Jacob Astor VI, with John Jacob Astor, 1st Baron Astor of Hever (born 1886) John Jacob Astor V. Sir John Jacob Astor (born 1918), youngest brother of David Astor, is John Jacob Astor VII, and the 3rd Baron Astor of Hever is John Jacob Astor VIII.

He was the son of John Jacob Astor IV (1864-1912) and Madeleine Talmadge Force (1893-1940), born without ever seeing his father who died when the RMS Titanic sank on April 15, 1912. His parents had married on September 9, 1911 and were returning home aboard the ship after more than eight months honeymooning in Egypt and Europe. Madeleine Astor was five months pregnant when her husband put her in one of Titanic's lifeboats and she was rescued eight hours after her husband went down with the ship.

Under the term of her extremely wealthy husband's will, Madeleine Astor received very little from an estate estimated to be as much as $100 million. Provided she did not remarry, nineteen-year-old Madeleine Astor received the annual investment income from a five-million-dollar trust fund and the use of their homes on Fifth Avenue in New York City and in Newport, Rhode Island. Because they were on their way home, and Mrs. Astor had conceived during their honeymoon abroad, no provision for the unborn child was made in his already set will. However, it is reported that their son received three million dollars at the age of maturity. The rest of her husband's estate was left to Vincent Astor, her late husband's son by his first wife.

John Jacob Astor VI graduated from St. George's School in Newport, following which he married Ellen Tuck French in 1934 with whom he had one son. Three years after their 1943 divorce he married Gertrude Gretch. The couple had a daughter but their marriage also ended in divorce in 1954. Astor VI married a third time to Dolores Fullman in 1954 who predeceased him.

John Jacob Astor VI died in Miami Beach, Florida in 1992 at the age of 79. His body was returned to New York for burial with his parents in the Trinity Church Cemetery.
