Mevo Beitar (Hebrew: מְבוֹא בֵּיתָר, lit. Beitar Gateway) is a moshav shitufi in central Israel. Located ten kilometres south-west of Jerusalem, it falls under the jurisdiction of Mateh Yehuda Regional Council. In 2007 it had a population of 327.
The village was established on 24 April 1950 by native Israelis and immigrants from Argentina who were members of the Beitar movement, including Matityahu Drobles, later a member of the Knesset. Located around a kilometre from the Green Line, it was a border settlement until the Six-Day War.
The settlement was founded on the land of the depopulated Palestinian village of Qabu.
