McTeague is a novel by Frank Norris. First published in 1899, it is set in San Francisco. The protagonist is a simple dentist named McTeague. The narrator never reveals McTeague's first name; he is referred to only as "Mac" by the other characters in the novel. In Erich von Stroheim's film adaptation, Greed, his first name is said to be John at one point, but there is no basis for this in the novel. The novel was also the basis of an opera by Robert Altman, William Bolcom, and Arnold Weinstein.
