A Day at the Races is a 1937 American comedy film, and the seventh film starring the Marx Brothers, with Allan Jones, Maureen O'Sullivan and Margaret Dumont. Like their previous Metro-Goldwyn-Mayer feature A Night at the Opera, this film was a major hit.

Irving Grant Thalberg was an American film producer during the early years of motion pictures. He was called "The Boy Wonder" for his youth and ability to select scripts, choose actors, gather production staff, and make profitable films, including Grand Hotel, China Seas, A Night at the Opera, Mutiny on the Bounty, Camille and The Good Earth. His films carved out an international market, "projecting a seductive image of American life brimming with vitality and rooted in democracy and personal freedom", states biographer Roland Flamini.
