Zionist political violence refers to acts of violence or terrorism committed by Zionists in support of establishing and maintaining a Jewish state in Palestine. These actions have been carried out by individuals, paramilitary groups, and the Israeli government, from the early 20th century to the present day, as part of the ongoing Israeli-Palestinian conflict.

Haganah was the main Zionist paramilitary organization that operated for the Yishuv in the British Mandate for Palestine. It was founded in 1920 to defend the Yishuv's presence in the region, and was formally disbanded in 1948, when it became the core force integrated into the Israel Defense Forces shortly after the Israeli Declaration of Independence.
