The Legislative Assembly of Rhodesia was the legislature of Southern Rhodesia and then Rhodesia from 1924 to 1970.

Southern Rhodesia was a landlocked self-governing British Crown colony in southern Africa, established in 1923 and consisting of British South Africa Company (BSAC) territories lying south of the Zambezi River. The region was informally known as south Zambesia until annexed by Britain at the behest of Cecil Rhodes's British South Africa Company, for whom the colony was named. The bounding territories were Bechuanaland (Botswana), Northern Rhodesia (Zambia), Portuguese Mozambique (Mozambique), and the Transvaal Republic.
