Maoz Haim (Hebrew: מָעוֹז חַיִּים, lit. Haim's Fortress) is a kibbutz in Israel. It is located adjacent to the Jordan River in the Beit She'an valley and falls under the jurisdiction of Valley of Springs Regional Council. In 2022 it had a population of 505. Aside from agriculture, the kibbutz also has a plastics factory, "Poliraz".

The kibbutz was established in 1937 by immigrants from Poland and Germany and was named after Haim Shturman, a member of the Hagana, who was killed there in 1938.

Maoz Haim was established on what was traditionally land belonging to the Palestinian village of Al-Ghazzawiyya.

South of the kibbutz is a small (11 dunam) nature reserve of Balanites aegyptiaca trees, called the Hurshat Zakum (Maoz Haim) reserve, declared in 1968. Zakum is the Hebrew name of the tree. This is probably the northernmost occurrence of these trees in the world.

A 3rd-century synagogue was discovered in February 1974 during construction work near Maoz Haim. It is an unusual archaeological find in that it attests to a record of synagogue development from a time of otherwise sparse historiography, in times of anti-Judaic legislation. It is situated in a large settlement where it served as a center of worship for Jews until destruction by fire sometime in the early 7th century.
