Ancient synagogues in Israel refers to synagogues in the modern State of Israel, built by the Jewish and Samaritan communities from antiquity to the Early Islamic period.

The Migdal Synagogue or Magdala Synagogue is the name used for the first of two ancient synagogues discovered at the ancient city of Magdala in Israel, close to the shore of the Sea of Galilee. Both synagogues were in use in the Second Temple period, which places them among the oldest synagogues found in Israel.
