The flag of Crimea (Russian: Флаг Крыма, romanized: Flag Kryma; Ukrainian: Прапор Криму, romanized: Prapor Krymu; Crimean Tatar: Qırım bayrağı) is the flag of the Autonomous Republic of Crimea claimed by Ukraine and the Republic of Crimea claimed by Russia. The flag was officially adopted on 24 September 1992 as the flag of the Autonomous Republic of Crimea, readopted on 21 April 1999, then readopted on 4 June 2014 as the flag of the Republic of Crimea, annexed by Russian Federation. The flag is a triband, striped horizontally in blue–white–red. The blue stripe is located at the top edge and is 1/6 of the flag's width. The white stripe is the largest of the three and is 2/3 of the flag's width, and the red stripe is located at the bottom edge and is 1/6 of the flag's width. When flown vertically, the flag's blue stripe should be at the left, the white field in the centre, and the red stripe on the right. The flag's length is twice its width.
