Kahanism is an nationalist ideology based on the views of Meir Kahane, founder of the Jewish Defense League and the Kach party in Israel, who said that the State of Israel must defend itself against its enemies. Kach has been designated as a terrorist organisation by Israel,Canada, the European Union and the United States.

The central claim of Kahanism is that the vast majority of the Arabs of Israel are now, and will continue to be, enemies of Jews and Israel itself, and that a Jewish theocratic state, governed by Halakha, absent of a voting non-Jewish population and including Israel, the West Bank, Gaza Strip, areas of modern-day Egypt, Jordan, Lebanon, Syria and even Iraq should be created.

According to Kahane, the term "Kahanism" is used primarily by those ignorant of Torah Judaism to discredit his ideology^{[citation needed]}, which he asserted to be rooted in Halakha^{[citation needed]} and the same as Torah Judaism.^{[verification needed][better source needed]} "Meir Kahane did not hate the Arabs – he just loved the Jews", said his widow Libby in her November 20, 2010 TV interview.
