The Amalgamated Clothing and Textile Workers' Union of South Africa (ACTWUSA) was a trade union representing workers in the garment and fabric industries in South Africa.
The Garment Workers' Union of the Western Province hoped to join, but was rejected as it was regarded as a benefit society which did not represent workers' rights.
The Garment Workers' Industrial Union decided against joining.
Like its predecessors, it affiliated to the Congress of South African Trade Unions.
On 16 September 1989, it merged with the Garment and Allied Workers' Union of South Africa, to form the Southern African Clothing and Textile Workers Union.
