The Mbaasem Foundation is a foundation established by Ghanaian writer Ama Ata Aidoo in Accra, Ghana, in 2000. It is a nonprofit foundation dedicated to promoting the work of Ghanaian and African women writers, to "establish and maintain a writing place for women". In 2002 the rented headquarters of the foundation was "likened to the transformation of Ernest Hemingway's home in Chicago into a literary haven and museum".
The Mbaasem Foundation organizes writing contests within Ghana funded by the US Embassy of Ghana and The Royal Bank Ltd. One of its contests is the "Mbaasem Writing Contest for Girls", with GHC 1000 as the top prize. It has also been involved in international conferences for women writers. In 2013 (16–19 May), it collaborated with the Organization of Women Writers of Africa (OWWA), New York University (NYU), and the Spanish Fundación Mujeres por África (Women for Africa Foundation) to present a conference in Accra, Yari Yari Ntoaso: Continuing the Dialogue – An International Conference on Literature by Women of African Ancestry. Ghanaian writers and scholars such as Ama Ata Aidoo, Amma Darko, Ruby Goka, Mamle Kabu, Esi Sutherland-Addy and Margaret Busby were invited to speak at the event, and it was attended by other notable writers such as Angela Davis of the USA, Tess Onwueme of Nigeria, Natalia Molebatsi of South Africa, Yolanda Arroyo Pizarro of Puerto Rico, Véronique Tadjo of Côte d'Ivoire and Évelyne Trouillot of Haiti.
