Lazarus Immanuel Fuchs (5 May 1833 – 26 April 1902) was a German mathematician. He was born in Mosina (located in Grand Duchy of Poznań) and died in Berlin, Germany.

He is the eponym of Fuchsian groups and functions, and the Picard-Fuchs equation; Fuchsian differential equations are those with regular singularities. Fuchs is also known for Fuchs's theorem which states that if x0 is a regular singular point then the differential equation

has at least one solution of the form

for some σ to be determined. In some cases, there will be two linearly independent solutions of that form.
