The village was founded in 1831 by Swiss Mennonites German Reformists, and Irish Catholics. It was originally named 'Crogan's Corners' after the postmaster. When the citizens chose to incorporate as a village, the Irish suggested the name 'Shannon' because of the green fields around the area. As there was already a village named Shannon in the state, the Swiss Mennonites suggested 'Bluffton', after the similar community in Indiana. The infamous bank robber John Dillinger robbed the Bluffton Bank (now known as Citizens National Bank of Bluffton) of $6,000 on August 14, 1933. In 2011, Bluffton celebrated its 150th birthday with a series of town-wide events.

After outgrowing several smaller facilities, in 1995, Mid Bus relocated to a much larger manufacturing and assembly facility in Bluffton. The company was acquired by Collins Industries in 1998.
