Sha'alvim (Hebrew: שַׁעַלְבִים) is a religious kibbutz in central Israel and one of only two affiliated with Poalei Agudat Yisrael (Hafetz Haim being the other).

Located near the city of Modi'in-Maccabim-Re'ut, it falls under the jurisdiction of Gezer Regional Council.

[1] During the 18th and 19th centuries, the area of Sha'alvim belonged to the Nahiyeh (sub-district) of Lod that encompassed the area of the present-day city of Modi'in-Maccabim-Re'ut in the south to the present-day city of El’ad in the north, and from the foothills in the east, through the Lod Valley to the outskirts of Jaffa in the west.

[2] The kibbutz was founded on 13 August 1951 by a Nahal group from the Ezra movement, on lands of the depopulated Palestinian village of Salbit.

Until the Six-Day War it was a target of numerous attacks from the West Bank due to its proximity to the Green Line.
