The Danzig Research Society (German: Naturforschende Gesellschaft in Danzig, Latin: Societas Physicae Experimentalis, Polish: Gdańskie Towarzystwo Przyrodnicze) was founded in 1743 in the city of Danzig (Gdańsk), in the Polish-Lithuanian Commonwealth, and continued in existence until 1936. The Societas Physicae Experimentalis (Experimental Physics Society) is thus considered as one of the oldest research societies in Central and Eastern Europe.
