Josiah Litch (April 4, 1809 – January 31, 1886) was a Methodist Episcopal preacher in the New England region of the United States, who was best known for his connections with the Millerite movement, and for using Bible prophecy to predict a loss of power for the Ottoman Empire.

He attended Wesleyan Academy at Wilbraham and joined the Methodist Episcopal ministry as an itinerant minister in 1833.

[5] Sarah's father, William Barstow, was a fellow minister with the New England Conference of the Methodist Episcopal church.

Litch at first was hostile to Miller's prediction of the second coming of Jesus, but after reading he was converted into the Millerite movement.

In 1845, he was present at the Albany Conference where the Millerites who were opposed to the shut-door doctrine met to work out the meaning of the Great Disappointment, and determine the future of the movement.

Litch eventually worked with the Evangelical Adventists, and served as president of the American Millennial Association.
