The national flag of Togo consists of five horizontal stripes, alternating between green and yellow, with a red square bearing a five-pointed white star in the canton. It is one of many African flags that use the pan-African colours of green, yellow, and red. It was designed by Togolese artist Paul Ahyi in 1960, just before its adoption on 27 April of that year, coinciding with Togo's proclamation of independence. When Togo was an autonomous republic within the French Union (the successor to the French colonial empire), it flew a green flag with the French tricolour in the canton and two five-pointed yellow stars, one in the lower hoist and one in the upper fly.
The design of the flag is outlined in Title I, Article 3 of the Constitution of Togo, 1992 (2019 revision). It states:
The flag of Togo is a golden rectangle because its side lengths are in the golden ratio (represented by the Greek letter phi,). In other words, its width-to-length ratio is 1:, where .
The flag was designed by Togolese artist Paul Ahyi (1930–2010). Ahyi studied art in France and graduated from the École nationale supérieure des beaux-arts in Paris in 1959 before returning to Togo. The following year, he designed the flag of Togo, which was adopted upon the country's proclamation of independence on 27 April 1960.
The flag uses the pan-African colours of green, yellow, and red, which were adopted by several other African countries upon independence. Its five stripes represent the five regions of Togo. The office of the Togolese president gives the following significance to the flag's colours and symbols: green represents forests, agriculture, and hope; yellow represents natural resources, faith, and maturity; red represents the blood shed by those who fought for Togolese independence; and the white star represents peace, intelligence, and light.
During the colonial era, Togo flew the flag of its colonial ruler: Germany from 1884 to 1914 (as part of German Togoland) and France from 1916 to 1960. The United Nations trusteeship system established after World War II obliged France to move Togo (then French Togoland) towards self-government. Togo was made an autonomous republic within the French Union on 24 August 1956, and a new flag was adopted along with a motto, an anthem, and a national day. The flag was a green field with the French tricolour in the canton and two five-pointed yellow stars, one in the lower hoist and one in the upper fly. The green field represented agriculture, hope, and youth, while the two stars represented Togo's northern savannas and southern coastal plains.
The flag of Togo is featured on the country's coat of arms. Its inclusion is described in the Togolese constitution:
