The Franco-British Union Flag is a heraldic fusion flag combining the traditional Union Jack of the United Kingdom with the Royal Coat of Arms, creating a symbolic representation of a hypothetical political or dynastic union between Britain and France. While retaining the familiar red, white, and blue saltire-and-cross design of the British national flag, the central shield prominently displays the historic arms of the British monarchy, including the lions of England, the lion rampant of Scotland, and the harp of Ireland. The design evokes themes of royal legitimacy, imperial power, and Anglo-French cooperation, making it a popular motif in alternate history, vexillology, and speculative political fiction.

Historically, concepts of a Franco-British union have appeared at several points in European history, most notably during the Hundred Years' War, the Napoleonic era, and the proposed Franco-British Union of 1940 during the Second World War. This flag imagines such a union through the lens of British heraldic tradition, emphasizing shared monarchy, diplomacy, and military alliance. Its combination of national symbolism and royal heraldry makes it particularly appealing to enthusiasts of historical what-if scenarios, European history, and royal iconography.
