The Battle of Frisches Haff or Battle of Stettiner Haff was a naval battle between Sweden and Prussia that took place 10 September 1759 as part of the ongoing Seven Years' War. The battle took place in the Szczecin Lagoon (German: Stettiner Haff) between Neuwarp and Usedom, and is named after an ambiguous earlier name for the Lagoon, Frisches Haff, which later exclusively denoted the Vistula Lagoon.^[1]

Swedish naval forces consisting of 28 vessels and 2,250 men under Captain Lieutenant Carl Rutensparre and Wilhelm von Carpelan destroyed a Prussian force of 13 vessels and 700 men under captain von Köller.^[2] The consequence of the battle was that the small fleet Prussia had at its disposal ceased to exist. The loss of naval supremacy meant also that the Prussian positions at Usedom and Wollin became untenable and were occupied by Swedish troops.
