David Joseph Bonnar (born February 5, 1962) is an American Catholic prelate who has served as Bishop of Youngstown since 2020.

[4] He studied at Duquesne University in Pittsburgh, obtaining a Bachelor of Arts degree in social communications in 1984.

Three months later, on July 23, 1988, he was ordained to the Catholic priesthood at the Church of Saint Gabriel of the Sorrowful Virgin in Whitehall, which was his home parish.

[1][6] A spokesman for the diocese and fellow priest noted in 2020 how Bonnar "has shown himself to be a wonderful spiritual leader and a very competent administrator".

This was a precautionary measure after one priest in Pittsburgh tested positive for the COVID-19 virus, while another developed mild symptoms.
