McNabb is a village in Putnam County, Illinois, United States. The population was 285 at the 2010 census, down from 310 in 2000. It is part of the Ottawa Micropolitan Statistical Area. Just outside of McNabb is the Clear Creek Meeting House, one of the few surviving western Quaker meeting houses. The Meeting House once hosted local abolitionists, such as Benjamin Lundy. In 1900, the Indiana, Illinois, and Iowa Railroad wanted a station in Magnolia township. Hon. J. M. McNabb, at that time county judge, promoted it and the resulting station and town were named after him.
