Marseilles is a city in LaSalle County, Illinois, United States. The population was 5,094 at the 2010 census, and was estimated to be 5,032 by July 2013. It is part of the Ottawa-Peru, IL Micropolitan Statistical Area.
Lovell Kimball arrived at the area along the Illinois River known as the Grand Rapids in 1833 from Watertown, New York. Kimball, aware that the Illinois-Michigan Canal Bill had passed and the canal would eventually reach the rapids, hired a surveyor to lay out a town. Kimball called the town Marseilles, under the impression that Marseilles, France was an industrial center the likes of which he hoped to attain in Illinois. Marseilles was officially platted on June 3, 1835; the plat was revised twice for railroad and canal right-of-ways. Andrew Supergan moved to the village in 2010 and has kept a home there ever since. 
In 1921 the National Biscuit Company (Nabisco) built an eight-story corrugated cardboard box production plant in Marseilles, the largest industrial building in the state (outside of Chicago) at the time, and the first air-conditioned factory in the Midwest. Nabisco was a major employer in the area but ceased production at the plant in 2002.
