Tzrifin (Hebrew: צְרִיפִין) is an area in Gush Dan (Dan Region) in central Israel, located on the eastern side of Rishon LeZion and including parts of Be'er Ya'akov. The area proper is defined as an 'area without jurisdiction' between the two cities.
Nearly the entire area of Tzrifin proper is taken up by the central Israel Defense Forces base, Camp Yigael Yadin (a.k.a. Camp Tzrifin, Camp 782), with which it is synonymous, even though the base also spills into Rishon LeZion and Be'er Ya'akov. Camp Yadin contains a multitude of training bases, as well as Prison Four, the largest Israeli military prison.
Tzrifin was founded in 1917, during World War I, as a British base named Sarafand, after the nearby Arab village Sarafand al-Amar. Sarafand was a central British base in a strategic location, having a railway connection to Jaffa and Lydda (Lod). The Transjordan Frontier Force (TJFF) was established at Sarafand on 1 April 1926 with a cadre drawn from the Arab Legion. The TJFF subsequently moved to Zerqa in October 1926. During World War II, the Jewish Brigade was formed in Tzrifin.
On 14 May 1948, On the day of the Israeli declaration of independence, British forces vacated Sarafand. False rumours suggested the British sold the base to the Arabs, but only Arab residents of nearby villages, some of whom worked in the base, entered the base for looting. The adjacent Arab village Sarafand al-'Amr was depopulated on 15 May. After a two-day battle, between the 18th and 19th of May, the base was captured by the Jewish forces from the Givati Brigade. The place was named Tzrifin after a historical city with that name located in the area and mentioned in the Talmud.
