Heinrich Friedrich Karl Ludwig Burkhardt (15 October 1861 – 2 November 1914) was a German mathematician.

He famously was one of the two examiners of Albert Einstein's PhD thesis Eine neue Bestimmung der Moleküldimensionen.

[1] Of Einstein's thesis he stated: "The mode of treatment demonstrates fundamental mastery of the relevant mathematical methods" and "What I checked, I found to be correct without exception.

He attained a doctorate in 1886 in Munich under Gustav Conrad Bauer with a thesis entitled: Beziehungen zwischen der Invariantentheorie und der Theorie algebraischer Integrale und ihrer Umkehrungen (Relations between the invariant theory and the theory of algebraic integrals and their inverses).

He died in Neuwittelsbach/München, of a disease of the stomach, diagnosed about Easter 1914.
