Border, Breed nor Birth is a science fiction novella by American writer Mack Reynolds. It is the second in a sequence of near-future stories set in North Africa, which also includes Black Man's Burden (1961-1962), "Black Sheep Astray" (1973), and The Best Ye Breed (1978). Border, Breed nor Birth and the North Africa series have been called a "notable exception" to the indirect treatment of racial issues in 1960s science fiction magazines.
