Jules Lermina (27 March 1839 – 23 June 1915) was a French novelist, journalist and political activist. He began his career as a journalist in 1859, and aligned himself with the socialists, which earned him several years in prison, and also the support of Victor Hugo.

His first novels appeared under the pseudonym of William Cobb. He published extensively in his lifetime, and his works include adventure novels, including popular sequels to The Mysteries of Paris (Eugène Sue) and The Count of Monte Cristo (Alexandre Dumas}, as well as detective novels, stories inspired by his interest in the occult, a biographical dictionary and a dictionary of French slang (argot).
