John Walter Jones (April 14, 1878 – March 31, 1954) was a politician and farmer in Prince Edward Island, Canada.

Born in Pownal, he first ran for public office in the 1921 federal election as a Farmer-Progressive candidate, but failed to win a seat in the House of Commons of Canada.He was first elected to the Legislative Assembly of Prince Edward Island as a Liberal in 1935.

In 1943, he became the 20th premier of the province when Thane A. Campbell was appointed Chief Justice of the PEI Supreme Court.

He had to proceed by order-in-council because the lieutenant governor, as a prohibitionist, refused to give Royal Assent to the necessary legislation.

In 1947, his government broke a strike at Canada Packers, a meat-packing plant, by seizing the plant, employing strike-breakers and outlawing trade union affiliation with national or international unions in the name of "protect(ing) the farm interest".
