A diagonal tricolour of white, blue, and green with bands of proportions (3:1:2). In the white band a brown emblem combining a Basotho shield with an assegai (lance) and knobkierrie (club).
This flag was adopted following a military coup ousting the Basotho National Party from power. The colours of the previous national flag were taken from the Basotho National Party flag.
