Hyacinthe-Marie Simon dit Delorme (August 15, 1777 – March 13, 1814) was a seigneur and political figure in Lower Canada.
He was born in Saint-Denis, the son of seigneur Jacques-Hyacinthe Simon dit Delorme and Marie-Anne Crevier Décheneaux.
He inherited part of the seigneury of Saint-Hyacinthe on the death of his father in October 1778; his mother acted on his behalf until he reached the age of majority.
In 1810, Simon dit Delorme donated land for the construction of the Collège de Saint-Hyacinthe.
His cousin Jean Dessaulles and nephew Pierre-Dominique Debartzch also served in the assembly.
