Peter Anthony Libasci (born November 9, 1951) is an American Catholic prelate who has served as Bishop of Manchester since 2011.

In 2016 Libasci invited the Priestly Fraternity of Saint Peter, who exclusively celebrate the Tridentine Mass, to establish St. Stanislaus Parish in Nashua.

[7] In 2021 Libasci invited the Institute of the Good Shepherd, which also solely celebrates the Tridentine Mass, to establish a parish in Winchester.

The crimes allegedly occurred between 1983 and 1984 when he was serving as parochial vicar at Saints Cyril and Methodius Parish School in New York.

O'Connor said that Libasci fondled his genitals on "numerous occasions", including one instance when the boy was setting up the altar for mass.

[10] The lawsuit also named the Sisters of St. Joseph, the religious order running the school at the time, of neglecting to prevent the abuse.
