**Florian Pop** (born 1952 in Zalău) is a Romanian mathematician, a professor of mathematics at the University of Pennsylvania.

Pop received his Ph.D. in 1987^{[1]} and his habilitation in 1991, both from the University of Heidelberg. He has been a member of the Institute for Advanced Study in Princeton, and (from 1996 to 2003) a professor at the University of Bonn prior to joining the University of Pennsylvania faculty.^{[2]}

Pop's research concerns algebraic geometry, arithmetic geometry, anabelian geometry, and Galois theory. Kuhlmann, Kuhlmann & Marshall (2003) call his habilitation thesis, concerning the characterization of certain fields by their absolute Galois groups, a "milestone".^{[3]}

In 1996, Pop was awarded the Gay-Lussac–von Humboldt Prize for Mathematics,^{[4]} and in 2003 he was awarded the Romanian Order of Merit.^{[2]} In 2012 he became a fellow of the American Mathematical Society.^{[5]}
