John Middleton Clayton (October 13, 1840 – January 29, 1889) was a Republican carpetbagger to Arkansas, originally from Pennsylvania.

In 1888, he ran for the office of Arkansas's 2nd congressional district in the United States House of Representatives, going up against incumbent Democrat Clifton R. Breckinridge.

However, in one case in Conway County, four masked, armed white men stormed into a predominantly black voting precinct and, at gunpoint, stole the ballot box that contained a large majority of votes for Clayton.

Losing under such circumstances, Clayton decided to contest the election and went to Plumerville to start an investigation on the matter.

On the evening of January 29, 1889, an unknown assailant shot through the window to the room he was staying in at a local boarding house (still standing at 101 N. Springfield Street) and killed him instantly.
