Benjamin Raspail (16 August 1823 in Paris – 24 September 1899 in Cachan, Seine, now Val-de-Marne), was a painter-engraver and politician of the French Third Republic.
He was the son of François-Vincent Raspail.
Like his father, he was classed extreme-left and was also exiled to Belgium.
In 1874, following the death of Eugène Lavenant, Raspail took over as Mayor of Arcueil as "premier conseiller inscrit au tableau".
He also proposed the law to seize the crown jewels from the monarchy, which was passed on 11 January 1887.
He lost a leg, which had to be amputated, following a chase in Épinay by a stone-throwing mob.
Upon his death, Raspail bequeathed his estate in Cachan to become a retirement home for people with work-related disabilities, and also a museum which would house his father's political documents and painting collection, as well as his own painting collection.
