Johann Nepomuk Berger (11 April 1845, Graz – 17 October 1933) was an Austrian chess master, theorist, endgame study composer, author and editor. In September 1870, he won the first tournament in the Austro-Hungarian Empire at Graz. In 1875, he won a match against Alexander Wittek (14 : 4) in Graz, and drew a match with Paul Lipke (3½ : 3½) at Eisenach 1896. Berger was the first Austrian to win an important international correspondence tournament the Monde Illustré 1889–1892, and he did so with the result of 45 wins, no losses, and three draws.
