Louis-Zéphirin Moreau was a Canadian Roman Catholic prelate who served as the fourth Bishop of Saint-Hyacinthe from 1875 until his death in 1901.

He dedicated himself to his studies and later his ecclesial studies despite the fact that illness forced him to slow down his studies which impeded on his progress to ordination. But a benefactor, Jean-Charles Prince, Coadjutor Bishop of Montreal, saw him advance towards his ordination and he served as an aide to several bishops in the diocesan secretariat and later as a diocesan vicar general.
