The Cape Colonial Forces (CCF) were the official defence organisation of the Cape Colony in South Africa. Established in 1855, they were taken over by the Union of South Africa in 1910, and disbanded when the Union Defence Forces were formed in 1912.

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).
