In the article, for the first time, samples of Ukrainian artistic and biographical Kotlyarevskiana of the first decades of the 21st century are analyzed holistically in a typological and regional aspect. Biographical, cultural-historical, comparative, and psychological methods of scientific research are applied. The main object of study is the biographical literary, artistic and popular science works «The Choice of Captain Kotlyarevsky» (2020) by V. Dobryansky and «Ivan Kotlyarevsky: Between the Empire and Ukraine» (2021) by P. Kraljuk; contextual component of intelligence – biographical novels and essays of the latest writing «P. S. of Hryhoriy Skovoroda...» (2009) by M. Shtelmak, «All angels of the Triangle. Apocrypha of Grigory Skovoroda's Travels» (2012) by V. Eshkilev, «Black Apple» (2013) and «Moon, Moon» (2022) by S. Protsyuk, «Secret Agent Mykola Gogol» (2016) P. by Kraljuk, «Iron Water» (2021) by M. Layuk. They represent figures of the classics of Ukrainian literature, whose lives are connected with the Poltava region, and were created and published in the postmodern period. The intensification of scientific and literary-artistic biography (in particular, writer's) nowadays is noted, the humanitarian and civilizational importance of this process is emphasized; the academic, scientific, popular science, and artistic formats of purely literary biographies are outlined and the special spread of the biographical novel (a type of artistic biography) and creative biography (a popular historical-literary mix) is indicated; the term «creative biography» is used with a scientific and universal meaning that is remarkable for today. It has been noted that Poltava Kotlyarevskiana, as well as regional writer biographies in general, is currently actively developing; its creators – mainly writers from the western region of Ukraine – time biographical novels and historical-publicist essays to the jubilee dates of outstanding writers, rethink and often interpret freely their biographies, causing public resonance and discussions.P. Kralyuk and V. Dobryanskyi in their works dedicated to I. Kotlyarevsky subtly depict and interpret in an original way, ideologically actualize in an anti-colonial and civic-patriotic way the image and achievements of the «father» of Ukrainian literature, emphasize his psychoworld, the alleged splitting of the spirit, but integral soul, interpreted as a national cultural code that clearly resonates in the tragic present.
