Nikolaus Rüdinger (25 March 1832 – 25 August 1896) was a German anatomist born in Bingen am Rhein, in the Grand Duchy of Hesse (present-day Rhineland-Palatinate).

In 1855 he worked as a prosector at the University of Munich, where in 1870 he was appointed as a professor of anatomy and second curator of the anatomical institute.

Rüdinger is credited for introducing a new method for preservation of corpses in the dissecting room.

This procedure involved injections of carbolic acid mixed with glycerine and alcohol.
