Un tuf volcanique est une roche généralement tendre, résultant de la consolidation de débris volcaniques, généralement de taille inférieure à quatre millimètres, sous l'action de l'eau et formant un conglomérat. Dans le cas de strates de cendre volcanique consolidées de la même manière, on parle de cinérite.
