The Fatal Glass of Beer is a 1933 American pre-Code comedy short film starring W. C. Fields, produced by Mack Sennett, and released theatrically by Paramount Pictures.

Written by Fields and directed by Clyde Bruckman, the film is a parody of rugged stage melodramas set in the Yukon.

Pa Snavely, as portrayed by Fields, serenades a Royal Canadian Mounted Police officer with "The Fatal Glass of Beer", a mournful song detailing the evils of foul drink and bad companions in the big city.

Purporting to be in Alaska, Fields continually goes to the door, declaring "it ain't a fit night out for man or beast", only to be hit with a bucket of snow.
