The Flag of Saint Petersburg, Russia, is the official symbol representing the federal subject of Saint Petersburg within the Russian Federation. Adopted on July 14, 1998, it consists of three horizontal bands of equal width: white at the top, blue in the middle, and azure (darker blue) at the bottom. The flag's central blue band bears the city's coat of arms. The design draws inspiration from the historical flag of Peter the Great, who founded Saint Petersburg in 1703. The flag symbolizes peace, unity, and the city's rich history and connection to the sea.
