Moritz Abraham Stern (29 June 1807 – 30 January 1894) was a German mathematician.

Stern became Ordinarius (full professor) at Göttingen University in 1858, succeeding Carl Friedrich Gauss.

[1] Although Carl Gustav Jacobi preceded him (by three decades) as the first Jew to obtain a math professorial chair in Germany, Jacobi's family had converted to Christianity long before then.

As a professor, Stern taught Gauss's student Bernhard Riemann.

Stern was very helpful to Gotthold Eisenstein in formulating a proof of the quadratic reciprocity theorem.
