Calvin Fairbank, American minister and activist (d. 1898)
Calvin Fairbank (November 3, 1816 – October 12, 1898) was an American abolitionist and Methodist minister from New York state who was twice convicted in Kentucky of aiding the escape of slaves, and served a total of 19 years in the Kentucky State Penitentiary in Frankfort. Fairbank is believed to have aided the escape of 47 slaves.

Pardoned in 1849 after four years of his first sentence, Fairbank returned to his Underground Railroad work. He was arrested in 1851 with the aid of the governor of Indiana, who was enforcing the Fugitive Slave Law of 1850. Fairbank was convicted again in Kentucky and served the full sentence of 15 years.
