Columbia Township is a civil township of Van Buren County in the U.S. state of Michigan. The population was 2,588 at the 2010 census, down to 2,546 at the 2020 census.

Communities
There are three settlements in the township, none of them large.
- Breedsville is the only incorporated village, located in the southwest part of the township.
- Columbia was an unincorporated community platted in 1870.
- Grand Junction unincorporated, although it has a larger business district than Breedsville, is located in the northwest part of the township. It is so named because it is located at the junction of two railroad lines, though only one now survives. It was first settled by David Young in the fall of 1869 and platted on December 8, 1871
- Berlamont is an unincorporated crossroads community that straddles the eastern township boundary with Bloomingdale Township. It was formerly known as "Bear Lake Mills" and was a station on the now-defunct railroad between Bloomingdale and Grand Junction. It was centered around a sawmill built in 1857 by H. Anderson and Amos S. Brown.
The Kal-Haven Trail State Park goes through Columbia Township in an east–west direction, passing through both Berlamont and Grand Junction. The midpoint of the Kal-Haven trail is located in Bloomingdale.
