Stanisław Osada (April 14, 1869 - July 28, 1934) was a Polonia activist, Polish nationalist, and author. His writings are credited with raising the national consciousness of Polish immigrants in the United States. In 1919, following Herman Bernstein's open letter blaming Poles for organizing pogroms against the Jews, Osada published a translation of Bernstein's letter in many Polish American publications, accused him of stirring an anti-Polish campaign. Osada concluded his article with a threat of boycotting Jewish merchants in the United States.
