Paul-Pierre Henry (Paul Henry) ( August 21 1848 – January 4 1905) and his brother Mathieu-Prosper Henry (Prosper Henry) ( December 10 1849 – July 25 1903) were French opticians and astronomers.

They made refracting telescopes and instruments for observatories, and were involved in the origin of the Carte du Ciel project.

Between the two of them, they discovered a total of 14 asteroids. The Minor Planet Center credits their discoveries under "P.P. Henry" and "P.M. Henry", respectively.
