The Polish Democratic Society (Polish: Towarzystwo Demokratyczne Polskie or TDP) was a radical constitutionalist political organization established in Paris by émigrés from the Kingdom of Poland in 1832. While not explicitly socialist with respect to their political program, the Democratic Society nonetheless was influenced by French Utopian socialist thinking of the era and advocated the right of citizens to own land or other means of production.
The Polish Democratic Society continued in existence into the decade of the 1840s, when it was a leading voice for revolution in Galicia. It is recognized as a forerunner of the Polish socialist movement which culminated in the establishment of the Polish Socialist Party.
