The Muncy Abolition riot of 1842 occurred in April 1842 in Muncy, Lycoming County, Pennsylvania in the United States. The riot started as an attack on a schoolhouse where an abolitionist speaker, invited by local Quakers, spoke against slavery. The speaker and his host, Enos Hawley, were then attacked as they fled to Hawley's house. Eighteen men were initially arrested and charged for the riot. Thirteen men were convicted for their actions in the riot, but were ultimately pardoned by Pennsylvania Governor David R. Porter.
