Thomas Kinney (March 3, 1868 – May 15, 1912), nicknamed "Snake", was a Missouri state senator and organized crime figure in St. Louis in the early 20th century.

In the late 1880s, Snake Kinney was a neighborhood pool hustler and all-around crook when he entertained the idea for running for office.

By 1894, Snake Kinney ran a saloon at Second and Carr, which served as a headquarters for the "Ashley Street Gang", soon to be known as the Egan's Rats.

Kinney was able to turn out a staggering number of votes at the polls for the candidates of his choosing, due to the muscle of the Egan gang.

Kinney, despite his gangster roots, was known for creating landmark Missouri legislation curtailing child labor and limiting women to working only eight-hour days.

Kinney's brother-in-law Tom Egan suspected his 1910 defeat was the result of a double-crossing political ally named Michael Gill, who betrayed Snake to advance his own ambitions.
