Robert Jerome "Duke" Dunne (August 29, 1899 – May 18, 1980) was an American football player and coach, and state court judge in Illinois.

While his father was serving as governor, the younger Dunne attended high school in Springfield, Illinois, where he was a star athlete in track and football.

His brother Maurice graduated from Michigan's law school in 1917 and played for the Wolverines' baseball and football teams.

[9] At the end of the 1921 season, Dunne was selected as a first-team All-American by Norman E. Brown of the Central Press Association.

The 1926 team tied with Michigan for the Western Conference title and held Notre Dame to one touchdown.

"[12] Dunne coached the line at Harvard for five years, announcing his retirement from football in December 1930.

[14] When Dunne ran for re-election in 1939, the bar association committee on candidates endorsed his renomination by a vote of 1,558 to 226 with 88.94% rating him as fit.

He also called it "the most futile job he has known" in criticizing the lack of funding and resources to carry out the vital function.

[23] After retiring from the bench in 1976, Dunne became associate counsel with the law firm of McBride, Baker, Wienke, and Schlosser.

He was 80 years old at the time of his death and was survived by his wife, Margaret, three sons, Robert, Jr., Denis, and Albert Pyott, and a daughter, Carol D.
