James Harvey McClintock (February 23, 1864 – May 10, 1934) was an American teacher, journalist, volunteer cavalry officer in Roosevelt's Rough Riders, civil servant, radio broadcaster, author and historian.

James H. McClintock acquired an academic education in his native state, in San Francisco and Berkeley, and later graduated from the Normal School of Arizona at Tempe.

While residing in Tempe, when but twenty two years of age, he was made justice of the peace and at the same time was engaged in the publication of a paper and in the operation of a farm.

In April, 1898, while conducting a news bureau at Phoenix, he assisted Colonel Alexander O. Brodie and Captain William O. O'Neill in enrolling a cavalry regiment for the Spanish–American War.

McClintock's discharge from the Rough Riders did not close out his military record, for in June, 1902, he was elected colonel of the First Arizona Infantry.

He had installed six rural routes and had been largely responsible in securing for Phoenix the new federal building, erected at a cost of $170,000.

For eighteen years he was the editorial representative in Arizona of the Los Angeles Times and did much magazine writing and special literary work.

In June 1900, the marriage of Colonel McClintock and Dorothy G. Bacon of Palo Alto, California, a graduate of Stanford University was celebrated.

McClintock continued to live in Arizona until his poor health forced him to return to Los Angeles, California, where he died on May 10, 1934, at the age of 70.
