The Red Ensign or "Red Duster" is the civil ensign of the United Kingdom of Great Britain and Northern Ireland. It is one of the British ensigns, and it is used either plain or defaced with either a badge or a charge, mostly in the right half.

It is the flag flown by British merchant or passenger ships since 1707. Prior to 1707, an English red ensign and a Scottish red ensign were flown by the English Royal Navy and the Royal Scots Navy, respectively. The precise date of the first appearance of these earlier red ensigns is not known, but surviving payment receipts indicate that the English navy was paying to have such flags sewn in the 1620s.
