Out of Africa is a memoir by the Danish author Karen Blixen.

 It provides a vivid snapshot of African colonial life in the last decades of the British Empire.
 Blixen wrote the book in English and then rewrote it in Danish.
 The book has sometimes been published under the author's pen name, Isak Dinesen.
