Bricha (Hebrew: בריחה Translit.: Brikhah Translated: escape or flight) was the underground organized effort that helped Jewish Holocaust survivors escape post-World War II Europe to the British Mandate for Palestine in violation of the White Paper of 1939. It ended when Israel declared independence and annulled the White Paper.

The movement of Jewish refugees from the Displaced Persons camp in which they were held (one million persons classified as "not repatrifiable" remained in Germany and Austria) to Palestine was illegal on both sides, as Jews were not officially allowed to leave the countries of Central and Eastern Europe by the Soviet Union and its allies, nor were they permitted to settle in Palestine by the British.

In late 1944 and early 1945, Jewish members of the Polish resistance met up with Warsaw ghetto fighters in Lubin to form Bricha as a way of escaping the anti-Semitism of Europe, where they were convinced that another Holocaust would occur. After the liberation of Rivne, Eliezer and Abraham Lidovsky, and Pasha (Isaac) Rajchmann, concluded that there was no future for Jews in Poland. They formed an artisan guild to cover their covert activities, and they sent a group to Cernăuţi, Romania to seek out escape routes. It was only after Abba Kovner, and his group from Vilna joined, along with Yitzhak (Antek) Zuckerman, who had headed the Jewish Combat Organization of the Polish uprising of August, 1944, in January 1945, that the organization took shape. They soon joined up with a similar effort led by the Jewish Brigade and eventually the Haganah.
