Tzrifin () 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.
