Connelsville is an unincorporated community in Nineveh Township, Adair County, Missouri, in the United States.
History
Connelsville was laid out in 1902 next to the older town of Nineveh, soon after the railroad was extended to that point. The community's name is a transfer from Connellsville, Pennsylvania. A post office was established at Connelsville in 1902, and remained in operation until 1937.
