Michał Dymitr Tadeusz Krajewski (8 September 1746 – 5 July 1817), sometimes also referred to as Dymitr M. Krajewski, was a Polish writer and educational activist of the times of the Enlightenment in Poland. His 1784 book Podolanka became the most debated and published Polish novel of that year, and his next book, Wojciech Zdarzyński, is considered to be the first Polish science-fiction novel.
