Ivanhoe was a town in Franklin Township, Linn County, Iowa. It was founded by early Iowa settlers, and laid out as a town by Anton Cowles at the intersection of the Old Military Road and the Red Cedar River. It was laid out in 1838 and surveyed in 1841. Ivanhoe was never platted, though it did have its own post office from 1845–49. Unlike other towns founded around that time on the Old Military Road, Ivanhoe faded away; many of its residents relocated to Mount Vernon, Cedar Rapids, or Marion.
