The Cornhill Magazine (1860–1975) was a monthly Victorian magazine and literary journal named after the street address of the founding publisher Smith, Elder & Co. at 65 Cornhill in London. In the 1860s, under the editorship of William Makepeace Thackeray, the paper's large circulation peaked around 110,000. Due to emerging competitors, circulation fell to 20,000 by 1870. The following year, Leslie Stephen took over as editor. When Stephen left in 1882, circulation had further fallen to 12,000. The Cornhill was purchased by John Murray in 1912, and continued to publish issues until 1975.

Smith, Elder & Co., alternatively Smith, Elder, and Co. or Smith, Elder and Co. was a British publishing company which was most noted for the works it published in the 19th century. It was purchased by John Murray in the early 1900s, its archive now kept as part of the John Murray Archive at the National Library of Scotland in Edinburgh, Scotland.
