The Flag of Bermuda was adopted on October 4, 1910. As a British colony, it combines the British Red ensign with the Union Flag in the upper left corner, and the coat of arms of Bermuda in the lower right.

The Flag of Bermuda is unusual for a British colony because it uses a red instead of blue background; however red backgrounds were used by both Canada (pre-1965) and the Union of South Africa (1870-1905 Natal only) as their flags.
