Franz Gerhard Eschweiler (1796 – 4 July 1831) was a German botanist.
Eschweiler was born in Cologne in 1796, the son of a district judge.
He then turned to botany and worked on the material collected by Carl Friedrich Philipp von Martius in Brazil.
In recognition of this collaboration, the Brazilian shrub genus Eschweilera was named after him.
