'''Paul-Pierre Henry''' (21 August 1848 – 4 January 1905) and his brother '''Prosper-Mathieu Henry''' (10 December 1849 – 25 July 1903) were [[France|French]] opticians and [[astronomer]]s.

They made refracting [[telescope]]s 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 [[asteroid]]s.  The [[Minor Planet Center]] credits their discoveries under "P. P. Henry" and "P. M. Henry", respectively. The lunar crater [[Henry Freres (crater)|Henry Frères]] (Henry brothers) and the Martian crater ''[[Henry (Martian crater)|Henry]]'' are named after them. They were jointly awarded the first [[Valz Prize]] in 1877 for their sky charts designed to facilitate the search for [[minor planets]].<ref name="Valz-Prize" /><ref name="Maindron-1880" />
