Bumpass is an unincorporated area in Louisa County, Virginia, United States. Its post office is still in service. National Historical Places registered in Bumpass include the Duke House and Jerdone Castle. The latter is a plantation (now lakefront) where George Washington spent the night on June 10 during his 1791 Southern tour. The community was named for John T.
