Nicolas Bergeron (19 December 1975 – 15 February 2024) was a French mathematician who worked in Pierre and Marie Curie University in Paris.

Bergeron obtained his PhD at École normale supérieure de Lyon in the year 2000 under the supervision of Jean-Pierre Otal.

[1] Bergeron's main interests concerned the geometry and topology of locally symmetric spaces and arithmetic groups, as well as their cohomology,[2] and their connection to number theory, in particular to Hilbert's 12th problem.

[3][4] Some of his publications showed an interest in Oulipo, referencing An Attempt at Exhausting a Place in Paris by Georges Perec.

[6] Bergeron was latterly a member of the editorial board of the journal Publications Mathématiques de l'IHÉS.
