Treaty of Prenzlau, also called the Peace of Prenzlau, refers to several 15th‑century agreements between the Margraviate of Brandenburg and the Duchy of Pomerania over control of Pomerania‑Stettin and the Uckermark. Prenzlau is in the center of the Uckermark; older documents spell the name as Prenzlow.

First Peace (1448)
- After a war from 1445 to 1448, the Uckermark was divided: the south stayed with Brandenburg and the north with Pomerania, with the north to pass to Brandenburg if Pomerania’s ruling house died out.
- The peace was prepared in 1447 and signed on May 3, 1448.

Second War and Peace (1468)
- War restarted after Stettin refused to honor the 1466 Treaty of Soldin.
- Brandenburg attacked Pomerania‑Stettin, including the Uckermark.
- Most fighting ended with a truce in 1468, and Brandenburg kept the southern Uckermark. The truce was extended in 1469 at Petrikau.

Second Treaty (1472)
- On May 31, 1472, Albert III, Elector of Brandenburg, and the Dukes of Pomerania agreed that Pomerania‑Stettin would belong to Brandenburg, the Uckermark would be part of Brandenburg, and the rest of Pomerania‑Stettin would become a Brandenburgian vassal.
- Emperor Frederick III confirmed this in 1473.

Third Treaty (1479)
- This treaty confirmed the 1472 agreement.
