Micajah "Big" Harpe (c. 1768 – August 1799) and Wiley "Little" Harpe (c. 1770 ~ 1804) were murderous outlaws who operated in Tennessee, Kentucky, and Illinois in the late 1700s.
After the atrocities committed by the Harpes, many members bearing the family name changed their name in some way to disguise their family heritage.See the entry for Darringer NotHarpe, for example
