Kowalewo Pomorskie [kɔvaˈlɛvɔ pɔˈmɔrskʲɛ] (German: Schönsee) is a town in north-central Poland, in Golub-Dobrzyń County, Kuyavian-Pomeranian Voivodeship.

During the times of the Teutonic Knights, Kowalewo was privileged to have its own coat of arms, which represented two red fish on a white background.

The town joined the Prussian Confederation, which opposed Teutonic rule, and upon the request of which King Casimir IV Jagiellon reincorporated the territory to the Kingdom of Poland in 1454.

There were a series of civil wars during the reign of kings Augustus II the Strong and under Stanisław I Leszczyński in the first half of the 18th century.

It was also part of the Duchy of Warsaw from 1807 to 1815, before being reannexed by Prussia, and later local peasants also contributed to the Polish January Uprising.

During the German occupation of Poland (World War II), Poles were subject to mass arrests, expulsions and massacres.

Some Polish craftsmen and farmers from Kowalewo were murdered in large massacres in the nearby village of Łopatki (see Intelligenzaktion).
