The Palestine Land Development Company (PLDC), also Palestine Land Development Corporation, was a program of the practicalist movement in early Zionism, particularly in the decade before the start of World War I. The PLDC worked to purchasing land, to train Jews in agricultural pursuits, and to establish Jewish agricultural settlements in Palestine.
The PLDC was founded in 1908, and by the outbreak of World War I it had purchased about 50,000 dunam (about 4600 hectares) of land. It was attempting to purchase nearly 3 times that amount in the Jezreel Valley, however the outbreak of the war prevented it from making such a purchase.
