Cornelius Springer Hamilton (January 2, 1821 – December 22, 1867) was a lawyer who was a U.S. Representative from Ohio, serving from March 4, 1867 until his death.

Hamilton was elected as a Republican to the Fortieth Congress and served from March 4, 1867, until his death, December 22, 1867.

Hamilton was beaten to death by his apparently deranged son, Thomas, with a board while the two fed livestock at the family farm in Marysville.

Thomas Hamilton then pursued his mother, younger brother John, and members of the local community with an axe, injuring but not killing anyone else.
