En informatique, Performance Application Programming Interface (PAPI) est une API (Interface de programmation) portable (sous la forme d'une bibliothèque logicielle) permettant d'accéder aux compteurs matériels spécifiques aux microprocesseurs modernes. PAPI est utilisé pour collecter des informations de bas niveau (telles que le nombre d'opérations en virgule flottantes FLOPS par seconde, le nombre de cache misses durant l'exécution d'un code, etc..). PAPI est interfacé avec les systèmes d'exploitation de type UNIX.
La bibliothèque PAPI est actuellement capable d'accéder les compteurs matériel de la plupart des processeurs modernes. La liste des processeurs non reconnu ne cesse de diminuer.
