The study is the first attempt to map putting on stage of Mozart's operas and singspiels in Bohemia from the late 1780s till 1900 outside Prague. It focuses on theatre troupes that included Mozart's pieces in their repertory, on their directors and singers, as well as the places, where they performed. The information is drawn from such sources as archival official documents, collections of theatre posters in archive and museum collections, notes in contemporary press, contemporary theatre almanach, etc. As much as 106 performances of Mozart's scenical pieces were found, of which the most frequent were 'Don Giovanni' (35×), 'Die Zauberflöte' (32×) and 'Le nozze di Figaro' (25×). With regard to the fact that the article was written within a larger research looking closely at theatre activity in the Bohemian regions in the nineteenth century, the author is convinced that the list of locations, where professional execution of Mozart's opera could have taken place, is complete. Less guaranteed (especially in the period until the mid-nineteenth century) is the completeness of the titles performed, and their rendering - there could have been more of these.
