The Maid of Sker is a three-volume novel that was written by R. D. Blackmore and published in 1872. The novel is set in the late 18th century and is about an elderly fisherman who unravels the mysterious origins of a foundling child who is washed ashore on the coast of Glamorganshire, South Wales. It was published subsequent to Blackmore's Lorna Doone, although he had begun writing The Maid of Sker 25 years earlier. Blackmore considered The Maid of Sker to be his best novel.
