Luigi Bettazzi (26 November 1923 – 16 July 2023) was an Italian prelate of the Catholic Church who was bishop of Ivrea from 1966 to 1999.

[2] He was ordained a priest on 4 August 1946 by Giovanni Cardinal Nasalli Rocca di Corneliano of Bologna.

"[2] Yves Congar described Bettazzi's contributions to the debate as "given at great speed and with fire", calling for clearly expressing "the idea that consecration confers all the powers and that it brings the bishop into the episcopal body" or collegium and does not depend upon any papal action.

[8] On 16 November 1965, he joined 41 other bishops in signing the Pact of the Catacombs, promising in "housing, food and means of transportation to live in accordance with the ordinary manner of our people" and to "renounce forever wealth and the appearance thereof".

Bettazzi nevertheless lived in the bishop's residence in Ivrea but never wore the ring Pope Paul VI gave to each Council participant, calling it "ostentatious".

"[12] In 2007 he endorsed a proposal of the Italian government to establish legal recognition for same-sex relationships called civil unions.
