A kibbutz (Hebrew: קיבוץ; plural: kibbutzim: קיבוצים, "gathering" or "together") is an Israeli collective community. Although other countries have had communal enterprises, in no other country have voluntary collective communities played as important a role as the kibbutzim have played in Israel; indeed, kibbutzim played an essential role in the creation of Israel.

There's even a 160 person fully anarchist Kibbutz Samar.
