|Flag of FIAV|
|Adopted||September 3, 1967|
|Designed by||FIAV Congress Committee (modified design by Klaes Sierksma)|
The flag of the International Federation of Vexillological Associations, or the Fédération internationale des associations vexillologiques, also called, and most commonly referred to as, FIAV, consists of a blue background with a yellow stylized halyard knot.
The halyard knot represents vexillology, since the halyard knot is often used to raise a flag on a flagpole.
