It isn't, actually, according to Nintendo canon. The video game creators have never specified a last name for Mario and his brother Luigi. They have, on several occasions, suggested that the two do not have a last name.
The last name of Mario as being also Mario, making him Mario Mario and his brother Luigi Mario, was devised by the screen writers for the live-action film "Super Mario Bros" (1993). This was their way of saying that the two are actually brothers with the last name Mario. This was never seen as the intent of the video game creators, who were only naming games, and continued with such similar themes as "Dr. Mario" (arcade) and "Super Smash Bros." (video game).
