Octavia Estelle Butler was born on June 22, 1947, in Pasadena, California, the only child of Octavia Margaret Guy, a housemaid, and Laurice James Butler, a shoeshine man. Butler's father died when she was seven, so Octavia was raised by her mother and maternal grandmother in what she would later recall as a strict Baptist environment. Growing up in the racially integrated community of Pasadena allowed Butler to experience cultural and ethnic diversity in the midst of racial segregation. She accompanied her mother to her cleaning work, where the two entered white people's houses through back doors, as workers.

Most critics praise Butler for her unflinching exposition of human flaws, which she depicts with striking realism. The New York Times regarded her novels as "evocative" if "often troubling" explorations of "far-reaching issues of race, sex, power". The Magazine of Fantasy and Science Fiction called her examination of humanity "clear-headed and brutally unsentimental" and Village Voice's Dorothy Allison described her as "writing the most detailed social criticism" where "the hard edge of cruelty, violence, and domination is described in stark detail." Locus regarded her as "one of those authors who pay serious attention to the way human beings actually work together and against each other, and she does so with extraordinary plausibility." The Houston Post ranked her "among the best SF writers, blessed with a mind capable of conceiving complicated futuristic situations that shed considerable light on our current affairs."  Scholars, on the other hand, focus on Butler's choice to write from the point of view of marginal characters and communities and thus "expanded SF to reflect the experiences and expertise of the disenfranchised." While surveying Butler's novels, critic Burton Raffel noted how race and gender influence her writing: "I do not think any of these eight books could have been written by a man, as they most emphatically were not, nor, with the single exception of her first book, Pattern-Master (1976), are likely to have been written, as they most emphatically were, by anyone but an African American." Robert Crossley commended how Butler's "feminist aesthetic" works to expose sexual, racial, and cultural chauvinisms because it is "enriched by a historical consciousness that shapes the depiction of enslavement both in the real past and in imaginary pasts and futures."  Butler has been praised widely for her spare yet vivid style, with Washington Post Book World calling her craftsmanship "superb". Burton Raffel regards her prose as "carefully, expertly crafted" and "crystalline, at its best, sensuous, sensitive, exact not in the least directed at calling attention to itself."
