Annie Shepherd Swan, CBE (8 July 1859 – 17 June 1943) was a Scottish journalist, novelist and story writer, who wrote mainly under her maiden name, but also as David Lyall and later Mrs Burnett Smith.
As a popular writer of romantic fiction for women, she published over 200 novels, serials, short stories and other fiction between 1878 and her death in 1943.
She has been called "one of the most commercially successful popular novelists of the later nineteenth and early twentieth centuries".
Swan was politically active throughout her life: during the war effort of the First World War, as a suffragist, as a Liberal activist, and as a founder-member and vice-president of the Scottish National Party.
