Jasienica (German: Jasenitz) is a district of Police, Poland, a town in the Pomerania Region.

In the High and Late Middle Ages, the village was the site of Jasenitz Abbey, now in ruins.

In Jasienica there is a confluence of the Gunica - a small river used as a kayak-way from Węgornik through Tanowo, Tatynia and Wieńkowo.

Gunica flows into Oder in the north part of the town of Police.

Each year at the end of August there is Augustinian Fair (Polish: Jarmark Augustiański) organized in the area of ruins of the abbey, with parade residents of the estate in historical costumes, lectures, artistic performances and stalls with traditional products.
