The Flag Institute is a membership organisation and UK-registered educational charity devoted to the study and promotion of flags and flag flying. It documents flags in the UK and around the world, maintains a UK Flag Registry, and offers advice and guidance about flags and their design and usage. It is often consulted on these matters but holds no official status or authority.
