The flag of Udmurtia is one of the official state symbols of the Udmurt Republic, along with its emblem and anthem.

The appropriate law N26-РЗ "On the National Flag of the Udmurt Republic" appeared on 30 April 2002.

The width of the vertical and horizontal cross-bars of the solar sign is equal to one third of the side of this imaginary square.

[6] Prior to the national revival in Udmurtia, the national movements in the Udmurt ASSR used a white flag with red and black stripes on the bottom edge, with a black ideogram on a white field.

The flag was based on a poem by Udmurt national poet V. Vladykin Why a Tyuragay Sings (Russian: Отчего поёт тюрагай).

Designs by V. Kovalchukov and E. Shumilov which sought to combine the Udmurt national colours with the Russian tricolour.
