Paviken is a lake in Västergarn on the western side of the island of Gotland.

During spring and autumn it is a stop-over site for migratory birds; a total of 240 species have been observed in the area.

[4][5] During the Viking Age, Paviken was a sheltered bay and cove connected to the Baltic Sea by a narrow strait.

Subsequently, the harbour and commercial activity were moved to nearby Västergarn harbor.

Dating from the early 1960s, archaeological investigations have found remains of port facilities, buildings and burial grounds.
