The Gulf of Euboea or Euboean Gulf (Greek Ευβοϊκός κόλπος, Evvoïkós kolpos ) is an arm of the Aegean Sea between the island of Euboea, which forms the north-east coast of the Gulf, and the Greek mainland in the southwest. The diagonal from northwest to southeast Golf is divided by the Strait of Strait of Euripus at Chalcis.

The northern Gulf of Euboea is about 80 km long and up to 24 km wide, the southern Gulf of Euboea is about 48 km long with a maximum width of 14 km.

Euboea was once connected at its northern tip to the geologically related mainland, and there was a land bridge over the Euripus.
