Bernard Pierre (1920–1997) was a French mountaineer, notable as a climber and an expedition leader.
Born in Chelles, Pierre was trained as a lawyer and ran his family's textile business, and was a mountaineer on the side.
He made the second ascent of the Piz Badile's northeast face, and was a lead climber on the first ascents of a route on the Aiguille des Aigles and the face of the Aiguille de la Brenva.
In 1952, he led a French-American expedition including Claude Kogan to the Andes, and made the first ascent of Salcantay.
He was part of the group which set out from a high camp towards the summit on 28 August 1953 but he could not continue to the top because he had not fully recovered from being caught in an avalanche a few days earlier.
