Puchałowo [puxaˈwɔvɔ] is a largely abandoned village in the administrative district of Gmina Janowo, within Nidzica County, Warmian-Masurian Voivodeship, in northern Poland. It lies approximately 21 kilometres (13 mi) east of Nidzica and 47 km (29 mi) south of the regional capital Olsztyn.

As a result of a decision about the expansion of the Muszaki proving ground, the population of the village was resettled and most of the village razed to the ground. Only a few houses remains, making it very similar to what is left from Ulesie, which also was largely razed to the ground as a result of the proving ground expansion.
