Green, with a golden upward-pointed crescent and star
The flag of Mauritania is the common name for the national flag of Mauritania in north-west Africa. The flag was adopted on April 1, 1959. It was introduced under the instructions of Moktar Ould Daddah, and the subsequent constitution of 22 March 1959. It is almost unique among national flags as it does not contain any of the three most common flag colours; red, white, or blue - a distinction it shares with Jamaica.
The colors green and gold are considered Pan-African colors. Green is also used to symbolize Islam, and the gold for the sands of the Sahara desert. The crescent and star are symbols of Islam, which is the major religion in the nation. Some writers have also speculated that green symbolises a bright future, and growth. There is no official specification or construction sheet for the exact relative measurements of the star and crescent, although the flag's measurements are 2:3.

Unlike the seal, the exact flag is specified, not merely the right for a law to specify it at some later date. However, the flag has its official basis in the earlier constitution of 22 March 1959; no changes were made after the country's declaration of independence in 1960.
