The current city flag of Columbus, Ohio is a yellow-white-red vertical triband with the city seal on a blue field. Officially, the flag was adopted in 1929, although it is unknown if the flag was ever flown when it was first adopted.

The city's first flag was adopted in 1912. The design consisted of the seal on a blue field. The second and current flag replaced this flag in 1929, but an unofficial flag similar to the one officially defined in legislation rose to higher prominence. Instead of a yellow, white, and red tricolor, it had a red, white, and blue tricolor. It remains unknown how this flag came to be, but after this anomaly was discovered, the city began flying the correct flag.

A redesign of the flag began in 2020. During the George Floyd protests, city mayor Andrew Ginther requested changes to the flag due to its use of imagery related to Christopher Columbus.
