The flag of the Republic of Karelia (Russian: Флаг Республики Карелия, romanized: Flag Respubliki Kareliya, Karelian: Karjalan tazavallan valdivolline flagu, Veps: Karjalan Tazovaldkundan flag, Finnish: Karjalan tasavallan lippu) is the official state symbol of the Republic of Karelia.

The flag had a blue background with 7 silver stars, representing the Ursa Major constellation (Otava) on the upper left corner.

Instead of a constellation, Kallela used a silver rainbow with 53 columns (1 for each of the Karelian communities of the Republic) to represent the Aurora Borealis.

The green color on the flag symbolized the forests and nature of Karelia, black – the native land and sorrow, red – the blood of patriots, joy and fire.

In April 1940, the flag was created, which was a red background with the words "Karelo-Finnish SSR" in the top left corner, along with a golden hammer and sickle.

[8] In 1956, Karelia became an autonomous republic of the RSFSR again and had to change its flag, which was adopted on 10 October 1956.

[10]Flag designs of Jonas Heiska and Akseli Gallen-Kallela are still used by various ethnic and political organizations of Karelia to this day.
