Paul Antoine Aristide Montel (29 April 1876 – 22 January 1975) was a French mathematician.

Montel was a student of Émile Borel at the Sorbonne.

Henri Cartan, Jean Dieudonné and Miron Nicolescu were among his students.

Montel's most important contribution to mathematics was the introduction and systematic development of the notion of normal family.

The notion of normal family was a predecessor of the notion of compact space introduced by Pavel Alexandrov and Pavel Urysohn in 1929.
