Valeriu Traian Frențiu (25 April 1875 – 11 July 1952) was the bishop of the Eparchy of Oradea Mare of the Romanian Greek Catholic Church between 1922 and 1952.

Metropolitan Victor Mihaly de Apșa and bishops Demetriu Radu and Vasile Hossu were present.

Frențiu went on visits ad limina in 1923 and 1925, during the latter of which he was joined by Iuliu Hossu and Alexandru Nicolescu, as well as a number of laypeople.

Frențiu sponsored the activity of local Christian periodicals "Vestitorul" and "Observatorul", published in Oradea and Beiuș, respectively.

Following the death of Metropolitan Alexandru Nicolescu in 1941, he was appointed to the Archdiocese of Alba Iulia and Făgăraș, where he remained until his return to the Eparchy of Oradea Mare in 1947.
