Gouffre Mirolda is a karstic cave located in the Haut-Giffre[1] mountain range, in the commune of Samoëns, Haute-Savoie, France.

Reinforced by the SS Genève and the Thonon Tauping Club, fossil galleries and upstream tunnels enabled the network to reach a height difference of 1,143 m (3,750 ft) in 1988.

A new survey reduces the depth to -1661 m.[9] Its name is derived from the forenames of the Rhodanien cavers Michel Schmidt, Roland Chenevier, and Daniel Trouilleux, who were lost in a flood in Gournier Cave in November 1976.

[12] The Gouffre Mirolda is developed in Urgonian Limestone at its contact of the Hauterivian marl following the dip first (E-W), and then (S-W) towards the Giffre valley.

[1][4] As at the Gouffre Jean-Bernard, the upstream section of the Réseau Lucien Bouclier appears to be the oldest part of the system, with the base of the CD 11 developed following the incision of the Giffre valley.
