The Treaty of Soldin (German: Vertrag von Soldin) was signed on 21 January 1466 at Soldin (now Myślibórz) by the Brandenburgian elector Frederick II and the Pomeranian dukes Eric II and Wartislaw X. It was mediated by the town of Stettin (now Szczecin). The treaty temporarily settled a conflict about the succession of Otto III, Duke of Pomerania, who had died without issue: Emperor Frederick III, elector Frederick II as well as Eric II and Wartislaw X of Pomerania claimed to be the rightful heir of Otto's share of the Duchy of Pomerania.
