The Flags of the World Flag (Vexillology) is a symbolic banner used to represent the study and cataloguing of national, regional, and organizational flags worldwide. Rather than signifying a sovereign state or political movement, the flag functions as a meta-emblem of vexillology, the academic and enthusiast discipline devoted to the design, history, and meaning of flags. Designs associated with the Flags of the World concept typically emphasize simplicity and recognisability, often incorporating globes, multiple stylised flags, or heraldic elements to evoke global scope and comparative study.

The term Flags of the World is most closely associated with international vexillological reference works and online archives, particularly those that document and analyse flags from every region and historical period. As such, the Flags of the World Flag has emerged primarily in educational, academic, and hobbyist contexts rather than through formal adoption. Its use reflects the growth of vexillology in the late 20th and early 21st centuries, alongside the expansion of digital archives and international collaboration among flag scholars. Today, the flag serves as a visual shorthand for global flag studies and the broader cultural interest in flag symbolism and design.
