The Name Thessaloniki
From a Macedonian princess to a city on the Thermaic Gulf -- the story behind the name.
Thessaloniki Meaning: The Quick Answer
Thessaloniki is named after Princess Thessalonike of Macedon — daughter of King Philip II, half-sister of Alexander the Great, and wife of King Cassander, who founded the city in 315 BC and named it after her.
Her own name combines Thessalos (Θεσσαλός, “of Thessaly”) and nike (νίκη, “victory”) — “victory in Thessaly,” commemorating a Macedonian military victory there.
In Greek the city is Θεσσαλονίκη. Common variants in other languages include Salonica, Saloniki, and the Latinised Thessalonica.
The Princess Thessalonike
Thessalonike (Θεσσαλονίκη) was a Macedonian princess, born around 352 BC, the daughter of King Philip II of Macedon and his Thessalian wife Nicesipolis. That made her a half-sister of Alexander the Great, who shared the same father.
Her name was itself a commemoration. She was born around the time of a major Macedonian victory over the Thessalians, and Philip is said to have chosen a name that joined the two events together: Thessalos (“of Thessaly”) and nike (“victory”) — literally, “victory in Thessaly.”
From Princess to City
After the death of Alexander the Great, Thessalonike married Cassander, one of his generals, who went on to rule Macedon as king. In 315 BC, Cassander founded a new city at the head of the Thermaic Gulf by merging several existing settlements, and named it Θεσσαλονίκη in honour of his wife.
The name has stayed remarkably stable for more than two thousand years, passing through Roman, Byzantine, and Ottoman rule with only modest changes. The core — the princess's name — is still exactly what Greeks say today: Θεσσαλονίκη.
Over the centuries, other languages adapted the name to their own sounds, which is why the city has gone by several forms in different eras and tongues:
Θεσσαλονίκη (Thessalonike) -- the original name, given by Cassander in 315 BC
Thessalonica -- the Roman form, used in classical and biblical sources
Salonica / Salonika -- the shortened form common in trade and on old maps
Saloniki -- a widely used short form, and the root of this site's name
Thessaloniki -- the standard transliteration of the Greek name today
For all its later history — the Roman forum, the Byzantine churches, the Ottoman walls, the great rebuilding after the 1917 fire — the city has carried the same name a Macedonian king gave it for love of his wife. See how that history unfolded in our About Thessaloniki guide.
Why We're Called Saloniki.net
Saloniki is one of the city's oldest and most affectionate short names — the form used across the Balkans, in Sephardic communities, and on the old shipping routes of the Mediterranean. It is the same name, just worn smooth by centuries of everyday use. We chose it because it captures both the deep history of the place and the easy familiarity locals feel for their city.
A Name Carried Across Languages
Few cities wear their origin as openly as Thessaloniki. The name is not a place-description or a folk legend — it is a person, a real Macedonian princess whose family shaped the ancient world, and whose name itself recorded a victory in Thessaly.
That is why the meaning has never drifted. Whether you see it written as Thessaloniki, Thessalonica, Salonica, or Saloniki, every form points back to the same woman and the same idea: victory. It is a fitting name for a city that has outlasted empires and rebuilt itself again and again on the shore of the Thermaic Gulf.
