Ulesie is a small settlement in the administrative district of Gmina Janowo, within Nidzica County, Warmian-Masurian Voivodeship, in northern Poland. It lies approximately north-east of Nidzica and south of the regional capital Olsztyn.
The reason for the settlement being small is the decision to expand the Muszaki proving ground in this area. As a result, only a small bit of the village is inhabited while older houses no longer exist. A similar thing happened with the nearby Puchaà Âowo.
