The Dyhrn family is an old German noble family originally from Saxony.

The family was first mentioned in the 13th century and settled at an early stage in Prussia and Silesia. It was one of the most important, oldest and richest noble families of the Kingdom of Prussia.

The Dyhrn family had an important role in Silesian industry in the 18th and 19th centuries. It was known not just as the owner of several manufactures and mines, but also as one of the biggest landowners in Silesia.

The Lords of Dyhrn gained the title of Baron (Reichsfreiherr) in the 17th century from the Habsburg Monarchy and the title of Prussian and Bohemian Count (Reichsgraf) in the second half of the 18th century, which was also the golden age of this family. There are only a few members of this family still living.
