Chróstnik [ˈxrustnik] (German: Brauchitschdorf) is a village in the administrative district of Gmina Lubin, within Lubin County, Lower Silesian Voivodeship, in south-western Poland.

The village is originally mentioned as Old Polish Chrustenik (meaning shrubbery or brushwood) with the parish church under the patronage of a Boleslaw von Brauchitsch in 1222.

The Baroque Brauchitschdorf Palace was erected from 1723 to 1728 and enlarged in 1909.

After World War II the Red Army plundered the building.

[citation needed] A fire in September 1976 destroyed the building further.
