Caulonia or Caulon was an ancient city on the shore of the Ionian Sea near Monasterace, Italy.
At some point after the destruction of the city by Rome in 200 BC, the inhabitants moved to a location further inland where they founded Stilida which developed into the modern town Stilo.
Since 1863 AD the name Caulonia has also been used by the town 15km away formerly known as Castelvetere. The city changed its name to Caulonia in honour of the ancient city, which was mistakenly believed to have been located in its territory.
