Beit Alfa () is a kibbutz in the Northern District of Israel, near the Gilboa ridge. The kibbutz was founded in 1922 by Hashomer Hatzair volunteers. In 1940 some of the members, affiliated with Hashomer Hatzair, moved to Ramat Yohanan kibbutz, in exchange for supporters of Mapai from Ramat Yohanan. Its dairy was the first Israeli dairy to use robotic milking technology. The Beit Alfa Synagogue National Park in the nearby kibbutz of Heftziba, contains an ancient Byzantine-era synagogue, with a mosaic floor depicting the lunar Hebrew months as they correspond to the signs of the zodiac.
