Romani (floruit 1714) was a French adventurer involved in the Affair of the Poisons.
Romani was described as a person credited with great abilities in disguise and persuasion.
He was accused of having conspired with his lover Catherine Monvoisin to assassinate Angélique de Fontanges with poisoned gloves, while he was valet-de-chambre to a lady of the court.
It was further claimed that he planned to assassinate Louis XIV by handing him a petition impregnated with poison.
He was pointed out for his participation in this affair by Marguerite Monvoisin, who described him as a poisoner and a master of disguises.
