John Davis Lodge (October 20, 1903 – October 29, 1985) was an American film actor, lawyer, politician, and diplomat. He was the 79th governor of Connecticut from 1951 to 1955, and later served as U.S. ambassador to Spain, Argentina, and Switzerland. As an actor, he often was credited simply as John Lodge. He had roles in four Hollywood films between 1933 and 1935, including playing Marlene Dietrich's lover in The Scarlet Empress and Shirley Temple's father in The Little Colonel. He starred or co-starred in many British and European films between 1935 and 1940.

Lodge was a member of four prominent political families in the Northeast United States: the Cabot, Lodge, Frelinghuysen and Davis families. He was a direct descendant of at least seven U.S. senators, and had many other politicians in his family, including his brother, Senator Henry Cabot Lodge Jr., who ran for Vice President of the United States in 1960 alongside presidential nominee Richard Nixon but was defeated by John F. Kennedy and Lyndon Johnson.
