The Mosiński Canal (Polish: Kanał Mosiński) is a canalized branch of the Obra River running entirely within western-central Poland.

It connects the Warta River at the village of Mosina (52°15′11″N 16°53′09″E / 52.253175°N 16.885720°E / 52.253175; 16.885720), then runs roughly east to an intersection with other Obra canals at a point north of Kościan 52°06′53″N 16°36′34″E / 52.114828°N 16.609389°E / 52.114828; 16.609389.

The canal has a length of about 26 kilometers, and was built in the middle of the 1800s.
