Black Sheep is a late Regency romance novel by Georgette Heyer which was published by The Bodley Head in 1966 and in the following year in the US by E. P. Dutton. The serial rights were also sold to Woman & Home. The novel was later described as combining "the warmer tone of her later books with the neat plotting of some of the earlier ones". Set in Bath, Somerset in 1816/1817, the story centres upon Abigail Wendover, the unmarried youngest daughter of a family dynasty and her interaction with Miles Calverleigh and his unscrupulous nephew Stacy.
