New Grub Street is a British novel by George Gissing published in 1891, which is set in the literary and journalistic circles of 1880s London. The story deals with the literary world that Gissing himself had experienced. Its title refers to the London street, Grub Street, which in the 18th century became synonymous with hack literature, although by Gissing's time, Grub Street itself no longer existed. Gissing revised and shortened the novel for a French edition of 1901.

George Robert Gissing was an English novelist, who published 23 novels between 1880 and 1903. In the 1890s he was considered one of the three greatest novelists in England, and by the 1940s he had been recognised as a literary genius. Gissing's best-known works have reappeared in modern editions. They include The Nether World (1889), New Grub Street (1891) and The Odd Women (1893). He retains a small but devoted group of followers.
