The Euripus Strait (
Greek: Εύριπος), is a narrow channel of water separating the
Greek island of
Euboea in the
Aegean Sea from
Boeotia in mainland Greece. It is subject to strong tidal currents which reverse direction several times a day. Its principal port is
Chalcis on Euboea, which is located at the strait's narrowest point.
