The flag of the British Windward Islands was the flag of the Federal Colony of the Windward Islands.
It was a Blue Ensign with the badge of the Governor-in-chief in the fly.
In 1903, the shape of the crown on the badge was changed slightly.
The Governor-in-chief of the Windward Islands used a Union Flag defaced with the badge.
The Federal Colony of the Windward Islands became the Territory of the Windward Islands in June 1956, and was dissolved in 1958.
