Jean-Paul Lemercier is a French climber and mountain guide with the Chamonix Guides Company.

Jean-Paul Lemercier is a childhood friend of climber Patrick Edlinger. In their late twenties, he and Patrick wanted to become mountain guides and racked up mountain climbs to prepare for the Aspirant Guide exam in France. Lemercier took the exam, while Patrick turned to pure rock climbing and told him, "I'm giving up on the exam; I don't want to take the place of someone who really wants to do this..."

Jean-Paul Lemercier can be found in climbing and mountaineering documentaries including "Objectif Mont-Blanc 4808m" by Stéphane Bizien (2011), "Le Mont Blanc" by Sébastien Devrient (2000), alongside Patrick Edlinger in "Opera Vertical" by Jean-Paul Janssen (1984), "Arrowhead" by Maurice Rebeix (1989), "Histoire D'Une Passion" by Bernard Maurice (1989).
