Czarnowo [t͡ʂarˈnɔvɔ] is a village in the administrative district of Gmina Pomiechówek, within Nowy Dwór County, Masovian Voivodeship, in east-central Poland.

French soldiers under the command of Marshal Louis-Nicolas Davout forced a crossing of the Wkra near Pomiechowo.

When they advanced eastward to Czarnowo they were fiercely resisted by Russian troops led by Lieutenant General Alexander Ivanovich Ostermann-Tolstoy in an all-night contest.

In the early morning hours of the 24th, Ostermann-Tolstoy ordered a retreat.
