The Parliament of the Cape of Good Hope functioned as the legislature of the Cape Colony, from its founding in 1853, until the creation of the Union of South Africa in 1910, when it was dissolved and the Parliament of South Africa was established. It consisted of the House of Assembly and the legislative council.

The Cape Colony, also known as the Cape of Good Hope, was a British colony in present-day South Africa named after the Cape of Good Hope. It existed from 1795 to 1802, and again from 1806 to 1910, when it united with three other colonies to form the Union of South Africa, then became the Cape Province, which existed even after 1961, when South Africa had become a republic, albeit, temporarily outside the Commonwealth of Nations (1961–94).
