Louis-Zéphirin Moreau (1 April 1824 – 24 May 1901) was a Canadian Roman Catholic prelate who served as the fourth Bishop of Saint-Hyacinthe from 1875 until his death in 1901.

[3] Their parish priest Charles Dion suggested that he could be academic rather than work in farming and so his parents sent him to learn Latin in his hometown under the schoolteacher Jean Lacourse.

Prince ordained him a week later on 19 December after an examination determined that Moreau had the adequate level of theological understanding.

Bishop Bourget returned in 1847 and Moreau became the cathedral's master of ceremonies while working in the diocesan secretariat; he also served as a chaplain to a convent of nuns.

In 1869 he was appointed as vicar general serving La Rocque in administration for the diocese and later in 1874 founded the Union Saint-Joseph to provide protection for workers from accidents or negligence.

However, the late La Rocque had once warned Archbishop Elzéar-Alexandre Taschereau that Moreau had some weaknesses in administration and instead recommended that the Bishop of Sherbrooke Antoine Racine succeed him.

He was consecrated on January 16, 1876 by the Archbishop of Québec with Bishops Louis-François Richer dit Laflèche and Édouard-Charles Fabre serving as the principal co-consecrators.

[2] Moreau created a court for matrimonial cases and in 1877 founded the Soeurs de Saint-Joseph and later the Sisters of Sainte Martha in 1883.

Moreau became titled as Venerable on 10 May 1973 after Pope Paul VI confirmed that the late bishop had lived a life of heroic virtue.

Moreau's beatification depended upon the papal confirmation of a healing deemed to be a miracle; a case that neither science nor medicine could explain.

members confirmed the case – based on the findings of the two previous boards – was indeed a miracle and that it would be submitted to the pope for final approval.
