The Oblast flag is a rectangular cloth (width to length ratio 2: 3) of crimson color with an image in the central part of the region's coat of arms.

It is fixed on a cylindrical base with a height of 1/20 of the flag's width.

The reference model of the flag is kept in the office of the speaker of the Oblast Council.

During the rule of the Tsardom of Russia, Russian Empire, and Soviet Union, Kharkiv did not have its own flag.

The banner consisted of a cross in a glow and above it two angels with trumpets holding a crown.
