Kazimierz Jerzy Skrzypna-Twardowski, Ritter von Ogończyk (b. October 20, 1866 in Vienna, Austria - February 11, 1938 in Lwów, Poland) was a Polish philosopher and logician.

Twardowski studied philosophy in Vienna with Franz Brentano and Robert Zimmermann. In 1891/1892 he received his doctorate with his dissertation Idee und Perzeption (Idea and Perception) and in 1894 his habilitation thesis Zur Lehre vom Inhalt und Gegenstand der Vorstellungen (On the Doctrine of the Content and Object of Presentations). He lectured in Vienna in the years 1894/1895 and then was appointed professor in Lwów (which at the time was still in Austria).

There Twardowski established the Lwów-Warsaw School of logic and became the "father of Polish logic", beginning the tradition of scientific philosophy in Poland. Among his students were the logicians Stanisław Leśniewski, Jan Łukasiewicz and Tadeusz Czeżowski, the historian of philosophy Władysław Tatarkiewicz, the phenomenologist and aesthetician Roman Ingarden, as well as philosophers close to the Vienna Circle like Tadeusz Kotarbiński and Kazimierz Ajdukiewicz.
