Weston is an unincorporated community located in McLean County, Illinois. It currently is still in existence, as opposed to its now-defunct namesake in DuPage County.
Weston was laid out 26 August 1867 by W. F. Bryan. The Original Town included 288 small lots, five blocks that were not subdivided and a Public Park. The depot and town hall were on the south side of the tracks. It was a station along the Toledo Peoria and Western Railroad. In 1895 there were four churches. Just east of town an area of natural tall grass prairie survives at Weston Cemetery Prairie.
