Antoni Stanisław Florian Waga (8 May 1799 – 23 November 1890) was a Polish zoologist, traveller, writer, literary critic and Piarist.
In 1820 he received a scholarship for his dissertation which supported a visit to the University of Berlin, Leipzig, Wittenberg, and Königsberg.
Waga worked under the patronage of Aleksander and Konstanty Branicki with other collectors including Franciszek K. Nowakowski and Władysław Taczanowski, travelling on collecting expeditions to Egypt, Nubia, Sudan, and Syria between 1862 and 1867.
He also described a fossil stag beetle Palaeognathus succini (1883) from Baltic amber and the salamander Salamandra caucasica in 1876.
He wrote biographies of several naturalists including those of Karol Perthées, Kluk, Alojzy Rafał Estreicher and Konstanty Tyzenhauz.
