Andrzej Sapkowski is a Polish fantasy writer, essayist, translator, and a trained economist. He is best known for his six-volume series of books The Witcher, which revolves around the eponymous "witcher," a monster-hunter, Geralt of Rivia. The series began with the publication of Last Wish in 1990 and was completed with the standalone prequel novel Season of Storms in 2013. The saga has been popularized through television, stage, comic books, and video games, and has been translated into 37 languages, making him the second most-translated Polish science fiction and fantasy writer after Stanisław Lem.

Born in Łódź, Sapkowski initially pursued a career as an economist after graduating from the University of Łódź. He turned to writing, first as a translator and later as an author of fantasy books, following the success of his first short story The Witcher, published in 1986 in Fantastyka magazine. Described as the "Polish Tolkien," he wrote ten novels and eight short story collections, which sold over 30 million copies worldwide. The influence of Slavic mythology is seen as a characteristic feature of his works. He is a five-time recipient of the Zajdel Award, Poland's most popular science fiction and fantasy prize, as well as many other awards and honors including the David Gemmell Award, World Fantasy Life Achievement Award, and the Gloria Artis Medal for Merit to Culture.
