Columbia Township is one of the twelve townships of Hamilton County, Ohio, United States. The 2010 census found 4,532 people in the township.[3]


Located in the eastern part of the county, the township has been divided into several "islands" by annexations. The principal ones have the following borders:

  • The largest western island (Ridge & Highland):
    • Silverton - northeast
    • Madeira - east
    • Cincinnati - everywhere else
  • The westernmost island (Ridgewood):

Most of Columbia Township is occupied by the following municipalities:

  • The city of Cincinnati (the county seat of Hamilton County), in the east
  • The village of Fairfax, in the center
  • The city of Indian Hill, most of the eastern half of the township
  • The city of Madeira, in the north
  • The village of Mariemont, in the south
  • The city of Milford, in the east
  • The city of Silverton, in the northwest

Some of the remaining township (only about 2.5 sq mi (6 km²) in area) is land unsuitable for development, especially the banks of the Little Miami River.

Name and history[edit]

Statewide, other Columbia Townships are located in Lorain and Meigs counties.


The township is governed by a three-member board of trustees, who are elected in November of odd-numbered years to a four-year term beginning on the following January 1. Two are elected in the year after the presidential election and one is elected in the year before it. There is also an elected township fiscal officer,[4] who serves a four-year term beginning on April 1 of the year after the election, which is held in November of the year before the presidential election. Vacancies in the fiscal officership or on the board of trustees are filled by the remaining trustees.
