The flag of the Chuvash Republic (Chuvash: Чăваш Республикин ялавĕ, Çovaş Respublikin yalavö; Russian: Флаг Республики Чувашия, Flag Respubliki Chuvashia), in the Russian Federation, is one of the official symbols of the Chuvash Republic, alongside the coat of arms and the State Anthem of the Chuvash Republic. The flag is a 5:8 yellow flag with a stylized red tree of life charged on the flag. The flag has been used officially as the flag of the Chuvash Republic since 14 October 1992. Prior to 1992, the Chuvash Republic existed as the Chuvash Autonomous Soviet Socialist Republic. Prior to 1937, Chuvash ASSR used a flag with traditional motifs of Chuvashia and the name of the ASSR. The motifs was deleted later in 1931 due to the traditional motifs being associated with chauvinism and bourgeois nationalism. After 1937, the flag of the Chuvash ASSR was identical to the flag of the Russian SFSR.
