Alojzy Feliński (1771 in Łuck - 1820 in Krzemieniec) was a Polish writer.
In his childhood he met Tadeusz Czacki. He was educated by the Piarists in Dąbrownica, later in Włodzimierz Wołyński. In 1778 he settled in Lublin, where he became a close companion of Kajetan Koźmian. Having resigned from the Bar together with Tadeusz Czacki, in 1779 he entered Parliament in Warsaw, where he became acquainted with many contemporary writers from Jacek Małachowski’s circle of friends. During the Kościuszko Insurrection, Feliński was Tadeusz Kościuszko’s secretary for French correspondence as well as the law and order commissar in Wołyń. After the defeat of the Insurrection he stayed at the Tarnowskis’ in Dzików, in 1795 he returned to Wołyń to manage his estate. In 1809 the author became a member of the Society of the Friends of Science. In 1815 he went to live in Warsaw and joined the circle of classicists. In 1818 he moved to Krzemieniec, where he took up the position of professor in the Krzemieniec Lyceum, where he subsequently became the headmaster. In 1819 he was granted honorary membership of Vilna University.
Feliński was a representative of the classicism typical of the time after Stanisław Poniatowski’s reign. One of his major works was the tragedy Barbara Radziwiłłówna (1817), regarded as a masterpiece of classicist poetics; he translated Dellile’s poem entitled The Landlord or the French Landowners. He often spoke about Polish orthography, entering into a polemic on the subject with Jan Śniadecki, who advocated traditional spelling.
