Bernhard Mühlig was a German landscape, genre and animal painter.

Bernhard Mühlig was the father of Albert Ernst Mühlig (1862-1909) and brother of Meno Mühlig (1823-1873). The artist studied painting at the Dresden Academy. From 1852 he exhibited his works at the Dresden art exhibitions. In 1853 Hermann Wilhelm von Witzleben commissioned the painter to capture the most beautiful motifs in small pictures during a hike together through Bohemia. Through an inheritance donation by Julie von Witzleben, Dresden, 50 of these paintings came into the possession of the Zwickau painting collection around 1900.

The brothers Bernhard and Meno Mühlig belonged to the Dresden circle of late romantics.
