John Thomas Caine (January 8, 1829 – September 20, 1911) was a delegate to the United States House of Representatives from the Territory of Utah.

Caine was elected as a Democrat to the Forty-seventh Congress to fill the vacancy caused by the action of the House declaring the Delegate-elect ineligible.

When LDS prophet and president Wilford Woodruff announced in his Manifesto of September, 1890 that the Church would not sanction any additional polygamist marriages, it was Caine who disseminated the information to members of Congress and the media in the Eastern US.

[2] Caine was an unsuccessful Democratic candidate for the position of first governor of the newly formed State of Utah in 1895 (the Act of Statehood took effect on January 2, 1896).
