Located just 1 kilometre (0.62 mi) north of the Gaza Strip, it is the namesake of the nearby Erez Crossing.

[1] Located in the northwestern Negev around 18 kilometres (11 mi) south of the coastal city of Ashkelon, it falls under the jurisdiction of the Shaʽar HaNegev Regional Council.

Erez is named after the first group that settled the kibbutz, who were members of the Noar HaOved from Petah Tikva.

Archaeological discoveries from Erez include a statue of a griffin with a Greek dedication by a priest, dating to 210/211 AD.

The kibbutz security team repulsed the attack in an hours-long battle, losing one of its members, Amir Naim.
