The flag of Kenya (Bendera ya Kenya) is a tricolour of black, red, and green with two white edges imposed with a red, white and black Maasai shield and two crossed spears. The flag is mainly based on that of Kenya African National Union and was officially adopted on 12 December 1963 upon Kenya's independence.

In the years following World War II, the Kenya African Union (KAU) introduced an organizational flag on 3 September 1951. The initial design consisted of a black and red bicolour featuring a central shield and arrow motif. In 1952, the design was revised into a tricolour of black, red, and green, incorporating a central shield crossed with a spear and arrow, along with the initials "KAU". The black stripe represented the African population, red symbolised struggle during the period, and green represented the land. The weapons motif reflected themes of resistance and collective action.
