Vineta or Wineta is an ancient and possibly legendary town believed to have been on the German or Polish coast of the Baltic Sea.

Traders of the 11th and 12th century reported about a town that was the most powerful port of the Baltic Sea. Bishop Adam of Bremen wrote that Vineta was the largest of all towns in Europe.

It is unclear whether Vineta really existed. Many archaeologists search for remains of the city along the Baltic Sea. It is claimed that Vineta sank into the sea due to a storm. The islands of Wolin and Usedom and the town of Barth claim to house the remains of Vineta. At all these places, Vineta museums and Vineta festivals try to attract tourists. Scientific evidence for the existence of the ancient town is still missing.
