Rudolf Jaromír Pšenka (March 21, 1875 - December 23, 1939) was a Czech-American writer, journalist, and political activist who was a leader in the emigrant Czech community in the United States. Born and raised in South Bohemia, Pšenka traveled to France in 1895 and then joined the French Foreign Legion, seeing action in North Africa. Afterwards he returned to France and then emigrated to Chicago, establishing relations with the Czech community there, particularly August Geringer, who had founded the daily newspaper, the Svornost. Pšenka married Geringer's daughter, became the editor of Svornost, and integrated into a group of exiles advocating for an independent Czechoslovakia, eventually helping found an office in Washington, D.C. that lobbied the American government to ensure the creation of the new nation at the conclusion of World War I.
