The national flag of Botswana (Setswana: folaga ya Botswana) consists of a light blue field cut horizontally in the centre by a black stripe with a thin white frame. Adopted in 1966 to replace the Union Jack, it has been the flag of the Republic of Botswana since the country gained independence that year. It is one of the few African flags that utilises neither the colours of the Pan-Africanist movement nor the colours of the country's leading political party.
