Chaim (Chajkel) Janowski (June 15, 1853 in Wołkowysk – 10 January 1935 in Tokyo) was a Polish chess master and organizer. Born into a Jewish family in Wołkowysk (then Russian Empire), he was the younger brother of Dawid Janowski. He was educated in Łódź (then so called Congress Poland) where lived and played chess for many years. Chaim twice took fourth in 1897 and 1898 (Wiktor Abkin and Gersz Salwe won), won followed by Samuel Rosenblatt, W. Abkin, Mojżesz Grawe, in 1899/1900, and took 3rd, probably behind Salwe and Akiba Rubinstein, in 1904/1905.
