Prison Four (Hebrew: כלא ארבע, Kele Arba), officially Confinement Base 394 (Hebrew: בסיס כליאה 394, Bsis Kli'a 394) was an Israeli military prison for Israeli soldiers, located in the military police compound in Tzrifin (Camp Yadin), Israel. It ws the main prison for military prisoners in Israel (the secondary being Prison Six) and could contain approximately 600 prisoners. It was the only prison for Israeli soldiers during an emergency. Prison Four accepted all prisoners except officers, senior NCOs, some military policemen and soldiers who serve in the Northern Command. These go to Prison Six. Both prisons were closed in 2021 and the prisoners were transferred to the new Neve Tzedek military prison within the Gur Camp complex near Kfar Yona.
