Seweryn Bialer (born November 3, 1926) is an emeritus professor of political science at Columbia University and an expert on the Communist parties of the Soviet Union and Poland. He was the Director of Columbia's Research Institute on International Change.
From May 1945 to June 1951 he was member of the Polish communist police force (the Milicja Obywatelska). He also held various positions in the Polish Communist Party (PZPR). He was a political officer of the State Police in Warsaw and a member of the Central Committee of the Polish Worker's Party. Subsequently, beginning in June 1951, he became a Professor at the Institute of Sociology and political editor of the newspaper Trybuna Ludu. He was also a researcher in economics at the Polish Academy of Sciences. During this time he authored several political science textbooks.
In January, 1956 Bialer defected to West Berlin and conducted almost one-year-long interview sessions for Radio Free Europe/Radio Liberty in New York, which was broadcast to Poland during that year.
He moved to New York, eventually receiving a Ph.D. in political science from Columbia. He was appointed Robert and Renee Belfer Professor of Political Science. In 1983 he was awarded a prestigious MacArthur Fellowship. He was elected a Fellow of the American Academy of Arts and Sciences in 1984.
