Norman Gary Finkelstein ( FING-kəl-steen; born December 8, 1953) is an American political scientist and activist. His primary fields of research are the politics of the Holocaust and the Israeli–Palestinian conflict.

Finkelstein was born in New York City to Jewish Holocaust-survivor parents. He is a graduate of Binghamton University and received his Ph.D. in political science from Princeton University. He has held faculty positions at Brooklyn College, Rutgers University, Hunter College, New York University, and DePaul University, where he was an assistant professor from 2001 to 2007. In 2006, the department and college committees at DePaul University voted to grant Finkelstein tenure. For undisclosed reasons the university administration did not tenure him, and he announced his resignation after coming to a settlement with the university.

Finkelstein rose to prominence in 2000 after publishing The Holocaust Industry, a book in which he writes that the memory of the Holocaust is exploited as an ideological weapon to provide Israel a degree of immunity from criticism. He is a critic of Israeli policy and its governing class. The Israeli government barred him from entry to the country for ten years in 2008. Finkelstein has called Israel the "Jewish supremacist state", and views it as committing the crime of apartheid against the Palestinian people. Through personal accounts in one of his books, he compares the plight of the Palestinians living under Israeli occupation with the horrors of the Nazis. Finkelstein's most recent book on Palestine and Israel, published in 2018, is Gaza: An Inquest into Its Martyrdom.
