Henry Kiddle (January 15, 1824 – September 25, 1891) was a United States educator who had an interest in spiritualism.

In 1843, he was made principal of a ward school, but two years later resigned to take charge of one connected with the Leake and Watts Children's Home.

He was made superintendent in 1870, but resigned in 1879, owing to an adverse public sentiment created by his avowal of a belief in spiritualism.

He has published in pamphlet form various addresses on education, modern spiritualism, and religious topics.

He edited several revisions of Goold Brown's English Grammar (last ed., New York, 1882) and other school textbooks, including a Text-Book of Physics (1883).
