John Fitch Kinney (April 2, 1816 – August 16, 1902) was a prominent American attorney, judge, and Democratic politician.

He was born in New Haven, New York, the fourth child and second son of Stephen Fitch Kinney (1789–1872) and Abby Brockway (1788–1824).

In February 1867, President Johnson appointed Kinney a Special Indian Commissioner to visit the Sioux.

He was appointed by President Arthur as agent of the Yankton Sioux in South Dakota, and served from December 11, 1884, until January 1, 1889, when he resigned, in order to escape the rigors of the northern climate, and again resumed the practice of law in Nebraska City.

He was Chairman of the Democratic Central Committee in 1896, when San Diego County was carried for William Jennings Bryan in the Presidential election, and at the close of his official term, in 1898, received from the County Convention a vote of thanks and an expression of confidence for the able and satisfactory manner in which he had discharged his duties.

Kinney was again married on May 9, 1899, to Lucy Jane Leonard (1826–1911), widow of Moses Thurston (1817–1873), a Mormon pioneer and old friend from Utah.
