Some view Puccini as essentially a "verismo" composer, while others, although acknowledging that he took part in the movement to some degree, do not view him as a "pure" "verismo" composer.

Puccini scholar Mosco Carner places only two of Puccini's operas other than "Tosca" and "Il tabarro" within the "verismo" school: "Madama Butterfly", and "La fanciulla del West."
