Plan Dalet (Hebrew: תוכנית ד', Tokhnit dalet "Plan D") was a Zionist military plan executed during the 1948 Palestine war for the conquest of territory in Mandatory Palestine in preparation for the establishment of a Jewish state. The plan was the blueprint for Israel's military operations starting in March 1948 until the end of the war in early 1949, and so played a central role in the 1948 Palestinian expulsion and flight known as the Nakba.
