John Kenneth McInnis (September 29, 1853 – October 21, 1923) was an educator, journalist, farmer and political figure in Saskatchewan, Canada.
He was born in Strathalbyn, Prince Edward Island, the son of John McInnis, and was educated at Prince of Wales College and the Central Academy in Charlottetown.
He served as principal at schools in Portage la Prairie, Manitoba, Moosomin and Wolseley.
He ran unsuccessfully for a seat in the House of Commons in the 1896 Canadian federal election in the Assiniboia West electoral district, tying his opponent and incumbent Nicholas Flood Davin, and subsequently losing on the tie-breaking vote of the Returning Officer, and would run again in 1908 Canadian federal election.
In 1913, he retired from journalism to pursue farming, real estate and a printing and publishing business.
