John Taylor Kean (March 11, 1857 – October 26, 1933) was an American politician.
For financial reasons he worked in different jobs until 1880 when he relocated to Lake Mills, Iowa, where he practiced as a lawyer.
In 1883 he completed a post-graduate course at the National Law School in Washington, D.C., and in 1884 he moved to Woonsocket in the Dakota Territory, where he worked as an attorney.
In this function he was the deputy of Governor Andrew E. Lee and he presided over the South Dakota Senate.
Kean later moved to Minneapolis, Minnesota, and then to La Jolla, California.
