Vachellia kirkii, formerly classified as Acacia kirkii, is a tree species native to tropical Africa, but now attributed to the genus Vachellia,[1] It is commonly known as the flood plain acacia.

[2] This species is a multi-trunked shrub or tree with a spreading, flat-topped crown.

[1] Vachellia kirkii is distributed across tropical Africa, from Guinea and Mali to the Democratic Republic Congo, Uganda, Kenya, Burundi, Rwanda, Tanzania, Angola, Zambia, and Zimbabwe.

It thrives in various habitats including woodlands, savannas, and mixed scrublands, often in seasonally-flooded areas near rivers and lakes.

[1] The species is named in honor of John Kirk, who accompanied David Livingstone on his Zambezi expedition in 1858.
