Nieznamierowice [ɲɛznamjɛrɔˈvit͡sɛ] is a village in the administrative district of Gmina Rusinów, within Przysucha County, Masovian Voivodeship, in east-central Poland.

The history of Nieznamierowice dates back to the early years of the Polish statehood, when on a small local hill stood a gord, protected by the Drzewiczka river.

In 1028, Nieznamierowice became a royal village, upon order of King Mieszko II.

It is not known when Znamierowice was granted Magdeburg rights town charter, but it probably happened in the 15th century.

Its name was changed to Nieznamierowice, and the newly established town became the seat of a St. Andrew Roman Catholic parish, which was transferred here in 1521 from Galki.
