Wacław Sieroszewski (1858 – 1945) was a Polish writer, Polish Socialist Party activist, and soldier in the World War I-era Polish Legions (decorated with the Virtuti Militari). For activities subversive of the Russian Empire, he had spent many years in Siberian exile.
Under the Second Polish Republic, Sieroszewski was a senator, and president of the Union of Polish Writers (Związek Zawodowy Literatów Polskich, 1927–30) and the Polish Academy of Literature (Polska Akademia Literatury, 1933–1939).
Sieroszewski's Siberian experiences became the subjects of his many stories and novels — Na kresach lasów (At the Edge of the Woods, 1894), Dno nędzy (The Depths of Misery, 1900), Risztau (1899), Ucieczka (The Escape, 1904), Zamorski diabeł (The Overseas Devil, 1900). He also authored the popular Bajki (Fables, 1910). His 12 lat w kraju Jakutów (12 years in the Yakut country, 1900) provides the first extensive etnographic account of the Yakut people.
