Krste Petkov Misirkov (Macedonian: Крсте Петков Мисирков, pronounced [kr̩'stɛ pɛ'tkɔf mi'sirkɔf]; Bulgarian: Кръсте Петков Мисирков; Serbian Cyrillic: Крста Петковић Мисирков; 18 November 1874 – 26 July 1926) was a philologist, journalist, historian and ethnographer from the region of Macedonia.
In the period between 1903 and 1905, he published a book and a scientific magazine in which he affirmed the existence of a Macedonian national identity separate from other Balkan nations, and attempted to codify a standard Macedonian language based on the central Western Macedonian dialects. Misirkov is regarded as the forefather of the Macedonian nation and for his efforts to codify a standard Macedonian language, he is often considered "the founder of the modern Macedonian literary language". A survey conducted in the Republic of Macedonia (now North Macedonia) found Misirkov to be "the most significant Macedonian of the 20th century".
