Laboratoire d'Annecy-le-Vieux de physique des particules

The Laboratoire d'Annecy-le-Vieux de physique des particules, usually abbreviated as LAPP, is a French experimental physics laboratory located in Annecy-le-Vieux in the Haute-Savoie department of France. It is associated with both the French particle and nuclear physics institute IN2P3, a subdivision of the CNRS research council, and the Université de Savoie.

The research activity of LAPP is historically linked with CERN, the European particle physics laboratory located near Geneva approximately 50 km from LAPP. However the laboratory has diversified beyond accelerator-based experiments into fields such as neutrino physics, gravitational wave detection space-based experiments.
