Dov Freiberg (15 May 1927 – 1 March 2008) born Berek Freiberg, was a Holocaust survivor, writer, and witness at the Eichmann trial and the Demjanjuk case. Freiberg was a prisoner at Sobibor extermination camp where he participated in the Sobibor prisoners' revolt. After the revolt, he managed to escape into nearby woods and survived until the Soviet Army entered in July 1944.

Dov Freiberg was born to Moses and Rebecca Freiberg in 1927 in Warsaw, Poland. The first years of his childhood were spent in the industrial city of Łódź, where his father was a factory worker. At the beginning of the Nazi occupation his father and brother tried to escape eastward, but his father was shot by the Germans when his convoy was attacked. A few months later his mother moved with her four children to her parents' house in Warsaw, which was situated in the ghetto that had been established in November 1940 in the heart of the Jewish Quarter. A year later, in autumn 1941, when conditions in the ghetto had worsened and tens of thousands of its residents had died or were killed, this spurred him to escape from the ghetto with the assistance of a smuggler; Freiberg escaped to the remote town Turobin in the district of Lublin, where the Jews, including the family of his father, lived with a sense of relative calm. On 17 May 1942, two days after his 15th birthday, the town was surrounded suddenly by the SS accompanied by local assistants and Ukrainians. Most of the town's Jews, along with the Jews of other nearby towns, were brutally deported to the Sobibor extermination camp.

Freiberg wrote four books including:

• Relic from Sobibor (in Hebrew: שריד מסוביבור), published in 1988, which tells his history from the outbreak of World War II, through the Holocaust, illegal immigration to Israel aboard the Exodus and up until the day of arrival in Israel. The book was a great success and was published in eight Hebrew editions, as well as in an English translation as To Survive Sobibor by Gefen Books.
• Journey to the Past with Gefen Shibolim was published in 1993 and describes his experiences with the campaign conducted by a group of high school students in 1991; the trip included a visit to Freiberg's first camp site Sobibor 48 years after his escaping from the camp.
• Be one person was published in 1996. It describes coping with life in Israel as a Holocaust survivor as well as his testimony at the Eichmann trial.
• Between Two Worlds was published in 2001. It describes the duality of his life between the world of the Holocaust and the world that followed after.
