The flag of the Donetsk Region (Ukrainian: Прапор Донецької області, Russian: Флаг Донецкой области), often referred to as the flag of Donbas(s) (Ukrainian: Прапор Донбасу, Russian: Флаг Донбасса), is the official flag of the Ukrainian region of Donetsk. It was designed by Nina Shcherbak (Ukrainian: Ніна Щербак, Russian: Нина Щербак), a Donetsk artist. The flag was officially adopted on August 17, 1999. The flag has proportions of 3:2, and is divided into two areas. In the upper part, there is a rising gold sun with 12 sunbeams in the upper steel blue part of flag (resembling the sky). In the lower black part (resembling the Donets Coal Basin) there are five gold ovals one under another (the reflection of the sun on the surface).
