Mossville, Illinois is an unincorporated community between Peoria and Chillicothe in Peoria County, Illinois. Mossville is part of the Peoria, Illinois Metropolitan Statistical Area and resides closely to the northern part of Peoria. Centered on the Illinois River valley and the end of Illinois Route 6 at Illinois Route 29, Mossville informally encompasses a number of different neighborhoods along the valley: Renchville, Brookview, a cluster of houses along the Illinois River referred to as "The Lanes", and Cedar Hills Estates, as well as the unincorporated village of 900 that can be considered Mossville proper. The Lake of the Woods subdivision, as well as Colony Point, both on the west bluff of the Illinois River valley overlooking Mossville, can also be considered to be part of the greater Mossville area. It was previously served by the Rock Island Line at Mossville Station.
