Adeline Sergeant (4 July 1851 - 4 December 1904) was an English writer. For several years she became a governess at Riverhead, Kent. In 1882, her novel Jacobi's wife resulted in a small award of £100, and the work was published serially in London. For the next several years her writings were serialized in the Dundee newspaper, where she lived from 1885-7. Adeline then moved to Bloomsbury, London, where she earned enough keep to support herself through her writings. In the late 1880s she developed an interest in Fabianism and the plight of the poor in London. Over her literary career, she produced over ninety novels, with some involving a religious theme.
