The Historical flags of the British Empire and the overseas territories refers to the various flags that were used across the various Dominions, Crown colonies, protectorates, territories which made up the British Empire and current overseas territories. Early flags that were used across the Empire (In particular the then Thirteen Colonies which would later become the United States of America) tended to variations of the Red and Blue Ensigns of Great Britain with no colonial badges or coat of arms attached to them.^[1] In the first half of the 19th Century, the first colonies started to acquire their own colony badges, but it was not until the UK Parliament passed the Colonial Naval Defence Act 1865 that the colonies were required to apply their own emblems.

The following list contains all former and current flags that were used across the Empire and as well as current British overseas territories until 1999.
