Diana, Princess of Wales, her companion Dodi Fayed and driver Henri Paul die in a car crash in Paris.

In the early hours of 31 August 1997, Diana, Princess of Wales, died from the injuries she sustained in a car crash in the Pont de l'Alma tunnel in Paris, France. Dodi Fayed, Diana's partner, and Henri Paul, the driver of the Mercedes-Benz W140 S-Class, were pronounced dead at the scene. Their bodyguard, Trevor Rees-Jones, was severely injured, but survived the crash.

Some media claimed the erratic behaviour of the paparazzi following the car, as reported by the BBC, had contributed to the crash. In 1999, a French investigation found that Paul, who lost control of the vehicle at high speed while intoxicated by alcohol and under the effects of prescription drugs, was solely responsible for the crash. He was the deputy head of security at the Htel Ritz and had earlier goaded paparazzi waiting for Diana and Fayed outside the hotel. Anti-depressants and traces of an anti-psychotic in his blood may have worsened Paul's inebriation. In 2008, the jury at a British inquest returned a verdict of unlawful killing through grossly negligent driving by Paul and the following paparazzi vehicles. Some media reports claimed Rees-Jones survived because he was wearing a seat belt, but other investigations revealed that none of the occupants of the car were wearing them.Diana was 36 years old when she died. Her death caused an unprecedented outpouring of public grief in the United Kingdom and worldwide, and her funeral was watched by an estimated 2.5 billion people. The Royal Family were criticised in the press for their reaction to Diana's death. Public interest in Diana has remained high and she has retained regular press coverage in the years after her death.

Diana, Princess of Wales (born Diana Frances Spencer; 1 July 1961 – 31 August 1997), was a member of the British royal family. She was the first wife of Charles, Prince of Wales—the heir apparent to the British throne—and mother of Princes William and Harry. Diana's activism and glamour made her an international icon and earned her enduring popularity as well as unprecedented public scrutiny, exacerbated by her tumultuous private life.

Diana was born into the British nobility and grew up close to the royal family on their Sandringham estate. In 1981, while working as a nursery teacher's assistant, she became engaged to Prince Charles, the eldest son of Queen Elizabeth II. Their wedding took place at St Paul's Cathedral in 1981 and made her Princess of Wales, a role in which she was enthusiastically received by the public. They had two sons, William and Harry, who were then second and third in the line of succession to the British throne. Diana's marriage to Charles suffered due to their incompatibility and extramarital affairs. They separated in 1992, soon after the breakdown of their relationship became public knowledge. Their marital difficulties became increasingly publicised, and they divorced in 1996.

As Princess of Wales, Diana undertook royal duties on behalf of the Queen and represented her at functions across the Commonwealth realms. She was celebrated in the media for her unconventional approach to charity work. Her patronages initially centred on children and the elderly but she later became known for her involvement in two particular campaigns, that involving the social attitudes towards and the acceptance of AIDS patients, and the campaign promoted through the International Red Cross for the removal of landmines. She also raised awareness and advocated for ways to help people affected with cancer and mental illness. The Princess was initially noted for her shyness, but her charisma and friendliness endeared her to the public and helped her reputation survive the acrimonious collapse of her marriage. Considered to be very photogenic, she was a leader of fashion in the 1980s and 1990s. Diana's death in a car crash in Paris led to extensive public mourning and global media attention. Her legacy has had a deep impact on the royal family and British society.
