John McCormick (August 17, 1893 – May 3, 1961) was an American film producer associated with the Hollywood studio First National Pictures.

He changed his mind in 1929 and placed Moore in her first sound film, titled Smiling Irish Eyes, which was not a great success.

[5] Years later, in an interview with her niece, Melinda, Moore described how McCormick had begun to turn down roles for her without her consent or even her knowledge.

[8] While in Hawai'i, he was linked romantically with British actress, Dorothy Mackaill, who had just called off her engagement to Neill Miller after their whirlwind romance.

[9] However, Mackaill sailed back alone to Los Angeles in May 1931, and about a week later McCormick married socialite, Janet Gettis, in 1931 in Honolulu, Hawai'i.
