Henry Baldwin Harrison (September 11, 1821 – October 29, 1901) was a Republican politician and the 52nd Governor of Connecticut.

[citation needed] Harrison ran for office as a Whig, and in 1854, he won a seat in the Connecticut Senate (4th District).

Active in the Whig Party, and author of the Personal Liberty Bill, he was instrumental in bringing about the nullification of the Fugitive Slave Law.

As Governor, he created the state Bureau of Labor Statistics, and he pushed for compulsory education to the age of 16 for Connecticut's children.

Harrison gave a moving eulogy at the funeral of his cousin, also a Governor of the State of Connecticut, Roger Sherman Baldwin.
