Monsignor Gabriel Piguet (born 24 Feb 1887 at Mâcon, died 3 July 1952 at Clermont-Ferrand) was the Roman Catholic Bishop of Clermont-Ferrand, France. Involved in Catholic resistance to Nazism, he was imprisoned in the Priest Barracks of Dachau Concentration Camp in 1944. He has been honoured as a Righteous Gentile by Yad Vashem, Israel's Holocaust Memorial. At Dachau, Piguet presided over the secret ordination of Blessed Karl Leisner, who died soon after the liberation of the camp. He survived his imprisonment, though physically diminished - he had lost 35 kg. He died seven years later.
