Kampsville was originally known as Beeman's Landing, after James L. Beeman, a ferry operator on the Illinois River. After Stephen Farrow (1802–1856) purchased the ferry from Beeman, the name was changed to Farrowtown. The name Vedder was used when the post office was established in 1857. The name Kampsville was made official on 6 March 1872 and refers to Michael A. Kamp (1829–1922), who served as president of the village board and was also a postmaster at Silver Creek, north of Kampsville.
