James Keegan O'Connor (1864–1922) was an Irish-American judge and Democrat politician from Utica, New York.

[1] He was a founder of the New York State Magistrates Association[2] and served as its president in 1912.

[5] He had a reputation as a supporter of all immigrants in Utica, who at the time accounted for around a third of its population.

The shooting of Italian mill workers by city police during a 1919 textile worker's strike likely played a role in the defeat of the incumbent mayor.

[6] A staunch Irish nationalist, he publicly spoke in favor of armed revolution against English rule in Ireland, and in the years before World War I called for an alliance between Ireland and Germany against England.
