The national flag of Algeria (Arabic: علم الجزائر, Berber: Acenyal n Dzayer) consists of two equal vertical bars, green and white, charged in the center with a red star and crescent. The flag was adopted on 3 July 1962. A similar version was used by the Algerian government in exile from 1958–1962. The Western blazon is per pale Vert and Argent; a crescent and star Gules.

Algerian ships fly it as their ensign, except for ships of the Algerian National Navy, which use one charged with two white crossed anchors in the canton as the naval ensign. Formerly, the two crossed anchors in the canton were red.

According to algeria-un.org, cited in 1999, the features of the flag are set down precisely, being described as:

The green must be a composition of equal yellow and blue having, according to the diagram of contrasts of Rood, a wavelength of 5.411 and the position 600 on the normal spectre. The red must be pure, of primary non-decomposable colour, and exempt of blue and yellow having, according to the above-indicated diagram, a wavelength of 6.562 and the position 285 on the normal spectre.
