His father Nahum Gantz Ostolish (1926–2005) came from Sovata (Szováta), in the more ethnically-Hungarian part of Transylvania, Romania, where his parents were Munkatsher Hassidim, a Haredi sect founded in Mukachevo (מונקאטש), Transcarpathia, then Hungary, now Ukraine.
He survived the Dragomirești Ghetto, Auschwitz, Harzungen and Woffleben[de], sub-sub-camps of Buchenwald.
Ostolish migrated to Palestine on the Arlozorov, an illegal aliyah ship.
British authorities in Palestine arrested Ostolish for trying to enter the country illegally.
He was an active member of the Labor Party and at one point a possible Knesset candidate.
He served as the mapainik (local representative of the Mapai party), a head of the moshav movement, and the community’s baal toke'a, blowing the shofar (ram's horn) on Rosh Hashana.
His parents were among the founders of Moshav Kfar Ahim, a cooperative agricultural community in south-central Israel.
In his youth, he attended the Shafir High School in Merkaz Shapira, and boarding school at the HaKfar HaYarok youth village in Ramat HaSharon.
According to his father, Benny Gantz was not religious and chose not to serve as the baal toke'a and does not know the Gaavad (chief rabbi of a rabinnical court) of Komemiyut (a nearby town in the Negev), but continued in his father's Zionist beliefs serving in the military, and holds "close to his heart" the memory of the Holocaust which Benny stated was present, "there, in the experience of the house".
Gantz is a graduate of the IDF Command and Staff College and the National Security College.
He holds a bachelor's degree in history from Tel Aviv University, a master's degree in political science from the University of Haifa, and an additional master's degree in National Resources Management from the National Defense University in the United States.
Gantz is married to Revital, with whom he has four children.
He lives in Rosh HaAyin.

In 2022, Gantz became the leader of National Unity, made up of the Israel Resilience Party and New Hope.
2019
In February 2019, an Israeli-American woman accused Gantz of exposing himself to her 40 years earlier, causing her traumatic disorders.
