Dominique Marie Jean Rey (born 21 September 1952) is a French prelate of the Catholic Church who was the Bishop of Fréjus-Toulon from 2000 to 2025.

In June 2013, he organized a four-day conference on sacred liturgy at the Pontifical University of the Holy Cross in Rome.

[12] An apostolic visitation of the diocese, ordered by the Dicastery for Bishops was announced on 7 February 2023,[13][c] and the investigators arrived on 13 February: Antoine Hérouard,[d] Archbishop of Dijon, assisted by Joël Mercier, secretary of the Dicastery for the Clergy, and a Curial official since 2002.

Its report expressed particular concern about how communities with questionable pasts were welcomed and about the conduct of missions to convert Muslims.

[16] On 21 November 2023, Pope Francis named Bishop François Touvet to serve as coadjutor bishop of Fréjus-Toulon and assigned him much of the authority Rey would normally have continued to exercise even when assisted by a coadjutor: "the special powers of the diocesan government in the areas of administration, management of the clergy, training of seminarians and priests, support of institutes of consecrated life, societies of apostolic life, and associations of the faithful".
