Greenview was laid out in October 1857, by Menard County pioneer Willian Engle, on land originally owned by Charles Montgomery in section 23 of township 19 north, range 6 west of the Third Principal Meridian. It was named after William G. Greene of nearby Tallula Precinct, because he convinced the railroad to come through the town: located on the Chicago, Alton & St. Louis Railroad, Greenview was incorporated by a special act of the Illinois General Assembly on May 6, 1869, then re-incorporated under the new general municipal laws of the state in March 7, 1877.
