Vineta is the name of a legendary city at the southern coast of the Baltic Sea. The legend evolved around traditions about the Medieval emporium called Jumne, Jomsborg, Julin or similar names by the chronicles, and with which Vineta is sometimes identified.

Jomsborg or Jómsborg was a semi-legendary Viking stronghold at the southern coast of the Baltic Sea, that existed between the 960s and 1043. Its inhabitants were known as Jomsvikings. Jomsborg's exact location, or its existence, has not yet been established, though it is often maintained that Jomsborg was located on the eastern outlet of the Oder river. Historian Lauritz Weibull dismissed Jomsborg as a legend.
