Arsène Lupin, Gentleman Burglar (French: Arsène Lupin, gentleman-cambrioleur) is the first collection of stories by Maurice Leblanc recounting the adventures of Arsène Lupin, released on 10 June 1907. It contains the first nine stories depicting the character, first published in the French magazine Je sais tout, the first one being on 15 July 1905. The seventh features English detective Sherlock Holmes, changed in subsequent publications to "Herlock Sholmes" after protests from Arthur Conan Doyle's lawyers, as seen in the second collection Arsène Lupin versus Herlock Sholmes.
