Founded in 1743, the community was so named on account of a flouring mill near the original town site. In 1940, the Pennsylvania guide, compiled by the Writers' Program of the Works Progress Administration, noted that regional farmers had previously come to the area to buy supplies and "have their wheat ground by the millers along the Wissahickon. Most of the houses are old, many dating to Colonial times. Flourtown's sole commercial activity is carried on by a few antique shops."
The Black Horse Inn was listed on the National Register of Historic Places in 2005.
