Slava Raškaj (; 2 January 1877 – 29 March 1906) was a Croatian painter, considered to be the greatest Croatian watercolorist of the late 19th and early 20th century. Deaf since birth, Raškaj was schooled in Vienna and Zagreb, where her mentor was the renowned Croatian painter Bela Čikoš Sesija. In the 1890s her works were exhibited around Europe, including at the 1900 Expo in Paris. In her twenties Raškaj was diagnosed with acute depression and was institutionalised for the last three years of her life before dying in 1906 from tuberculosis in Zagreb. The value of her work was largely overlooked by art historians in the following decades, but in the late 1990s and early 2000s interest in her work was revived.
