Nancy A. Collins is a United States horror fiction writer best known for her series of vampire novels featuring her character Sonja Blue. Collins has also written for comic books, including Swamp Thing, Jason vs. Leatherface, Predator: Hell Come A-Walkin' and her own one-shot Dhampire: Stillborn.

Collins has written 20 novels since 1989, many of which refer to and directly include races of creatures the author calls Pretenders, monsters from myth and legend passing as human to better hunt their prey.

Collins has also written a number of highly acclaimed Southern Gothic short stories and novellas, most of which are set in Seven Devils, Arkansas, a highly fictionalized version of her hometown.

Most recently, she has focused her attention onto the Golgotham urban fantasy series, published by Penguin. Golgotham is the "supernatural" ghetto of New York City, where creatures from myth and folklore--including witches, shape-shifters, leprechauns and centaurs--live and work in uneasy alliance with mankind.
