Acta Mediaevalia. Series Nova is an annual journal published by the Centre for Medieval Studies, affiliated with the John Paul II Catholic University of Lublin, Poland.

In its new form as an academic journal, Acta Mediaevalia. Series Nova publishes scholarly articles in thematic volumes, covering the Middle Ages (with particular reference to Central and Eastern Europe), as well as critical editions and book reviews, all of which fall within the chronological scope of ca. 700 – ca. 1550. Critical editions are published in Latin with introductions and commentaries in English. Articles and book reviews are published exclusively in English.
