Radacz [ˈradat͡ʂ] (German: Raddatz) is a village in the administrative district of Gmina Borne Sulinowo, within Szczecinek County, West Pomeranian Voivodeship, in north-western Poland.

The settlement was first mentioned in a 1403 deed, when the area was part of the Imperial Duchy of Pomerania.

After the Griffin dukes became extinct, Raddatz was incorporated into the Brandenburg-Prussian province of Pomerania in 1653.

The parish church was erected in 1744; it housed the personal carriage of the Polish king John III Sobieski, which was brought here by Field Marshal Henning Alexander von Kleist in the First Silesian War and rebuilt as a pulpit (today on display in the Museum of King John III's Palace at Wilanów).

The remaining German population was expelled and Radacz manor became a State Agricultural Farm (PGR).
