Leopold Heinrich Fischer (19 December 1817, Fribourg-en-Brisgau – 2 February 1886, Fribourg-en-Brisgau) was a German zoologist and mineralogist . He was the son of d’Aloys Fischer. He studied medicine at Fribourg-en-Brisgau but also at Vienna. Fischer practised medicine in Freiburg-in-Brisgau and from 1845 taught zoology and mineralogy there. Initially an assistant, he became a professor in 1859. His most significant works are:

He was one of the best specialists in the classification of insects of his time.

His collections are in the Naturhistorisches Museum in Vienna.
