Leśniewo [lɛɕˈɲɛvɔ] is a village in the administrative district of Gmina Srokowo, within Kętrzyn County, Warmian-Masurian Voivodeship, in northern Poland, close to the border with the Kaliningrad Oblast of Russia.

To the west of the village there is the Masurian Canal, near the village there are two unfinished sluices: Leśniewo Górne and Leśniewo Dolne.

Because of both World Wars, both attempts did not manage to finish those sluices.

A legend says that they were to be used for U-boats that would sail for repairs through the canal inland or for barges.
