Homer Stille Cummings (April 30, 1870 – September 10, 1956) was an American lawyer and politician who was the United States attorney general from 1933 to 1939.

Three years after entering private practice, Cummings supported William Jennings Bryan's 1896 presidential bid.

As a Progressive whose oratorical skills made him a dramatic trial lawyer, Cummings seemed a natural for the political arena.

As mayor, he helped construct and improve streets and sewers, reorganized the police and fire departments, and secured a shorefront park that later was named for him.

During his last year as county prosecutor, a vagrant and discharged army soldier, Harold Israel, was indicted for the murder in Bridgeport of Father Hubert Dahme, a popular parish priest.

[6] Despite police evidence that included a confession and a .32 revolver, which the suspect had and which produced a fired cartridge consistent with the bullet in the deceased, Cummings conducted a thorough investigation of the crime.

During the bitterly divided 1924 Democratic National Convention, Cummings tried to calm the delegates by formulating a compromise plank on the controversial issue of the Ku Klux Klan, which had been revived in the previous decade.

He strengthened the Federal Bureau of Investigation, called a national crime conference, supported the establishment of Alcatraz as a model prison for hardened offenders, and reorganized the internal administration of the department.

In 1937, Cummings published "We Can Prevent Crime", and, with Carl McFarland, an assistant attorney general, Federal Justice, a departmental history.

During his first week as attorney general, he advised Roosevelt that the Trading with the Enemy Act of 1917 permitted the president to close banks and regulate gold hoarding and export.

Frustration over the conservative nature of the Court, coupled with outrage over the proliferation of lawsuits and injunctions against the government, made Cummings eager to expand the judiciary.

In 1961, character actor Robert F. Simon appeared as Cummings in an episode of ABC's crime drama, The Untouchables.
