Direct answer
Diana was not a “Princess” in her own right at the moment of her death because she was no longer married to a Prince of Wales. As a commoner who had divorced the holder of the royal title, she did not retain the feminine version of that style. She remained a member of the royal family, a hugely popular public figure, and continued to be widely referred to as Princess Diana in everyday usage and in many official contexts, but her formal legal title changed after the divorce decree absolute.
What royal title did Diana hold at her death?
On 28 August 1996, the divorce decree absolute made Diana formally a “Diana, Princess formerly of Wales” rather than "Her Royal Highness The Princess of Wales." At the time of her death on 31 August 1997, her correct formal style was Diana, Princess of Wales, and not "Princess Diana" as a personal title. This distinction matters because she did not hold a peerage or royal style in her own right once the marriage ended, and the legal removal of her HRH status was part of the formal divorce arrangements.
The legal effect of divorce on royal styles
Under long-standing royal protocol and the 1917 letters patent issued by King George V, the title "Princess of Wales" is derived from and tied to the marriage. When that marriage ends, the specific royal style granted as part of the role is typically surrendered. Formal discussions in the years after 1996 included efforts to clarify whether the HRH and the style could be retained; the outcome was that she ceased to be styled as a Princess by birth or marriage, although the public and many institutions continued to use the familiar form. The monarchy and official institutions moved to address the correct forms of address in government and etiquette guides following her death.
The title she kept in practice
Although her formal HRH status was removed, Diana remained a senior working royal during her marriage, and in everyday conversation and much media usage she was and remains widely called "Princess Diana." In practice, many institutions and official programs still treat her as an honorary royal to this day. She was also still a member of the wider royal family by history and ongoing personal relationships, which contributed to the enduring public perception of her as a princess regardless of the precise legal change in 1996.
How the public and institutions refer to Diana now
In public memory, media coverage, and most cultural uses, Diana continues to be called Princess Diana. This reflects both her time as the wife of the Prince of Wales and the enduring popularity and recognition of that title. Government departments, museums, and many official bodies adopt the version "Diana, Princess of Wales" as the standard form to acknowledge her role and maintain clarity, while still recognizing the widespread use of Princess Diana in popular culture.

Frequently asked questions about Diana’s title
- Could Diana have kept the title after divorce? No. Under royal protocol, the title tied to the role was removed at the decree absolute, because it derived from the marriage.
- Was Diana ever a Princess in her own right? No. She was not born into royal blood or granted a personal peerage; her princess status came through marriage only.
- Why is she still called Princess Diana? Popular usage, her iconic role as Princess of Wales, and ongoing public perception sustain the familiar form.
- Did the palace object to the continued use of Princess Diana? The palace clarified correct forms but accommodated widespread usage, especially in charitable and memorial contexts tied to her work.
- Does her sons’ status affect her title? No. Her title derived from her marriage; her sons remain princes by birth, but that does not restore her own royal style.
Final summary of her status
To state it plainly at the intersection of law, etiquette, and public memory: Diana ceased to be a titled princess under royal protocol when the divorce was final in 1996. At the moment she died in 1997, her correct formal style was Diana, Princess of Wales, rather than Princess Diana as a personal rank. In practice, the public, media, and many institutions continue to use Princess Diana as a lasting nickname that reflects her global identity and enduring legacy. Understanding the distinction between formal title and popular usage clarifies why both descriptions remain common in different contexts.
