Gulf of Euboea
Open-knowledge reference entry

The Gulf of Euboea, Euboean Gulf, Euboic Sea or Euboic Gulf (Greek: Ευβοϊκός Κόλπος, romanized: Evvoïkós Kólpos) is an arm of the Aegean Sea between the island of Euboea (northeast coastline) and the Greek mainland (southwest coastline). Trending diagonally northwest–southeast, the gulf is divided by the narrow Strait of Euripus, at the town of Chalcis. The North Euboean Gulf is about 80 kilometres (50 mi) long and up to 24 kilometres (15 mi) wide, and the South Euboean Gulf is about 48 kilometres (30 mi) long, with a maximum width of 14 kilometres (9 mi).
North Euboean Gulf
The North Euboean Gulf (Greek: Βόρειος Ευβοϊκός Κόλπος, Voreios Evvoïkos Kolpos) separates the northern part of the island Euboea from the mainland of Central Greece (Phthiotis and Boeotia). The narrow Euripus Strait, near Chalcis, connects the gulf to the south with the South Euboean Gulf. To the northwest, the gulf is connected with the Malian Gulf at Cape Cnemides. The overall length is about 68 km (42 mi). Its total area is 1,060 km2 (410 sq mi), and its maximum depth is 450 m (1,480 ft), in its central part. The Lichades islands lie at the northwestern end of the gulf, and Atalanti Island near the southwest coast.
The main city on the North Euboean Gulf is Chalcis, at its southeastern end.

Why this record matters
“Gulf of Euboea” is worth following because a concise public description often conceals a longer documentary argument. Here, Gulf, Euboea and Open-knowledge provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Feb 24, 2026. The linked authority identifier is Q1536322. Authority coordinates are 38.550, 23.500. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
