The Angwa Sandstone is a geological formation of the mid-Triassic Cabora Bassa Basin [1] and Mana Pools Basin [3] of southern Africa, consisting mainly of sandstone.

[1] The Angwa Sandstone has been correlated to the Molteno Formation of the Great Karoo Basin, South Africa,[6][1] and to the Escarpment Grit of the Mid-Zambezi Basin.

[7] The formation is a sedimentary unit, consisting mainly of fluvial sands and silts.

[1] It has been dated as covering rocks from much of the Triassic, with pollen and flora identified from the Induan, and Ladinian to Norian.

[6][8] The Angwa Sandstone Formation is found in Mozambique, Zambia, Zimbabwe, in the Mana Pools and Cabora Bassa Basins.
