The Association of Concerned Africa Scholars (ACAS) is a US-based group of left-liberal Africanist scholars and students, founded in 1977.
In the early 1980s ACAS opposed Ronald Reagan's policy towards Africa, in particular towards South Africa. In the 1990s the Association led opposition to the Boren Bill.
The Association's papers are held at the African Activist Archive at Michigan State University.
